Preface

Surface acoustic wave (SAW) components from Siemens Matsushita Components rank among the key devices of modern information and communication technology. Fabricated in submicron technologies they are high-tech devices that feature not only outstanding precision, but also small size, high reproducibility and excellent long-term stability. SAW components are used as bandpass filters, as frequency-stabilizing devices and for complex signal processing functions. The following summary gives you a survey of our product line and points out the benefits of the individual filter groups.
q Intercarrier, quasi/split sound, video and audio filters

Sophisticated design and production processes create extremely high precision in the passband and excellent adjacent-channel selectivity. As a consequence no cost-intensive matching elements and extra traps are necessary. Switchable SAW filters for multistandard applications enable switching of the transfer function for different TV standards. These filters come in miniaturized plastic packages (SIP 5 K and DIP 10 K) ready for automatic processing.
q Satellite filters

Satellite filters are applied in analog and digital satellite receivers for channel filtering on the IF level. Dual-channel filters allow the reception of signals from two satellites with different transponder bandwidths. Yet another benefit is switchover when reception deteriorates in poor weather like rain and snow. The smaller bandwidth means better signal/noise ratio and higher selectivity and thus much improved picture and sound reproduction.
q Bandpass, vestigial sideband and spectrum-shaping filters

Telecommunications makes high demands: precise bandpass characteristics, flat passbands, steep skirts and high selectivity. SAW filters offer the tailored solution. They are used as bandpass filters in digital satellite and cable receivers, as vestigial sideband filters in TV transmitters, cable headends and transposers, and for spectrum shaping in digital radio relay systems.
q Clock recovery filters

In digital telecommunications, on coaxial copper or fiber-optic cable, the signal has to be regenerated at regular intervals to avoid bit errores. For this S+M Components offers standard SAW filters for the frequency range 50 through 2500 MHz, assuring reliable clock recovery even at high transmission rates.
q Resonators

SAW resonators are key components in remote control and telemetry systems. They are used in heating energy controllers, garage door openers and keyless entry systems for cars, to name just a few examples. SAW resonators work in the fundamental mode, from 200 through 900 MHz, allowing small and highly stable oscillator circuits. They come in hermetically sealed TO 39 or SMD packages, as one-port and two-port resonators, covering all common frequencies.
q Low-loss filters for mobile communication

For designers of cellular and cordless phones, low weight and low space requirements are the outstanding advantages of SAW filters. Our RF and IF filters come in miniaturized SMD packages down to a size of only 3,8 3,8 mm. The ultra-small DCC 6 package has a weight of no more than 0,07 g. Furthermore the filters can do without external matching elements and promote compact, low-power circuit design. Steep passband skirts of the filter improve speech quality; low insertion loss means less power consumed and thus longer battery life, or smaller and therefore lighter batteries.

Preface

This data book presents the current product range of Siemens Matsushita Components, with exemplary specification of typical standard types in full detail. Filters which are only listed in the surveys without further specification are marked by the sign #. Detailed information on these types can be obtained from your nearest Siemens Sales Office. Although the data book is intended to give comprehensive information about our product range, its focus is necessarily on standard products. Our special strength are custom filter solutions. With a special design software, devised in-house, and advanced CAD methods SAW filters can be rapidly designed and modified to customer specifications. If you have any questions, if you need information on special applications not covered in this data book, or applications engineering support, do not hesitate to contact your nearest Siemens Sales Office, Passive Components and Electron Tubes Group; an address list is contained in the last chapter.

Introduction

General Technical Information

Surface acoustic wave filters (SAW filters) are integrated, passive components with bandpass filter characteristics. Their operation is based on the interference of mechanical surface waves. Compared to coil filters, surface acoustic wave filters provide a series of favorable characteristics:
q q q q q q q

High reproducibility High performance Stable characteristics No adjustment required Amplitude response and phase response can be specified independently of each other Close tolerances of data Small space requirements (a complete TV IF filter only takes up 0,5 cm2)

The user of a surface acoustic wave filter has a component which fully replaces complex LC combinations and yields superior picture and sound quality. 1.1 Construction

A metal layer (Al) is vapor-deposited onto a single-crystal, piezoelectric substrate. Using a photoetching technique, the metal is removed to obtain fine, finger-like interspersed electrodes (interdigital transducers), which serve as piezoelectrical input and output transducers. The substrate is then bonded to a metal base and connected to the terminals by means of bonding wires. An absorber prevents surface waves reflected from the edges of the substrate from causing spurious signals. The SAW filter is encapsulated to protect it from external influences.

Operating principles of TV IF filters Fundamentals

When electrical signals are applied to the input transducer, it launches mechanical ("acoustic") surface waves which, due to reciprocity, in turn produce electrical signals in the output transducer. The transducers act as transmit/receive "antennas" for surface acoustic waves. Widely varying "antenna characteristics" can be achieved as a result of the transducer structure. The center frequency, amplitude response and group delay are determined by the number, length, arrangement and spacing of the transducer fingers (see para. 2.4). Superposing of the "antenna characteristics" of the input and output transducers results in the filter characteristic.

General Technical Information

All TV IF filters included in this book consist of transducers with constant finger widths and spacings. One of the transducers has constant finger lengths (unweighted or unapodized transducer) whereas the other one has varying finger lengths (weighted or apodized transducer). In most cases the first one operates as output transducer and the second one as input transducer. The transfer function of the unweighted transducer is sin(x)/x-shaped; its center frequency depends on the spacing of the fingers and its bandwidth on the number of the fingers. The higher the number of the fingers, the smaller is the bandwidth of the transducer. The finger widths range from 27 m (G 1962 M: IF 38,9 MHz) to 1,2 m (B 696: IF 480,0 MHz). The amplitude and group delay of a weighted transducer's transfer function can be set independently of each other. The transfer characteristic of the filter can be closely approximated by multiplying the transfer characteristics of the two transducers. 2.2 Phase velocity of surface acoustic waves

The phase velocity of surface acoustic waves is frequency-independent. Depending on the substrate material and the crystal cut, the phase velocity ranges from 3000 to 4000 m/s. 2.3 Chip size

The required chip size largely depends on the desired filter data. Narrowband performance, steep slopes and high group delay predistortion necessitate transducers with many fingers and, hence, with a long substrate. Filters with two inputs or outputs require broad substrates. 2.4 Filter design

The filter design is based on the specification of the filter and is performed in two steps. In the first step, the linear design, the center frequency and bandwidth of the filter are used to specify the unweighted transducer as well as the width and number of fingers for the weighted transducer. The finger lengths of this transducer, which determine its transfer function, are found by a linear optimization program (simplex algorithm). In this program, a smooth pass band, a tolerance scheme, continuity conditions, a Nyquist slope, single frequency points (e.g. color carrier) or derivatives of slopes (e.g. at the sound shelf) as well as the value to be optimized (e.g. stop band rejection or the amplitude of the color carrier) can be specified. If a solution is possible with respect to the given filter length, the algorithm finds the unique solution for which the specified conditions are satisfied exactly. If no solution is possible, the specifications must be relaxed or the filter length must be extended. In the filter just designed, none of the secondary order effects of a SAW filter have been taken into account, such as diffraction of the waves due to small radiating apertures (e.g. 0,1 to 15 wavelengths for G 1962 M), the influence of the circuitry (frequency-dependent voltage division on the load resistance), the distribution of electrical charges on the transducer fingers or reflection of the waves at the edges of the fingers. In the second step of design, these secondary order effects are calculated with the aid of a simulation program and their influence on the transfer function will be corrected by a predistortion in the weighted transducer. This modification of the transducer is performed by a least square optimization program. After compensation for the secondary order effects, the design of the SAW filter is complete, a mask can be made and the filter produced.

Characteristics

Surface acoustic wave TV IF filters are based on the interference of mechanical surface waves, i.e. on delay effects and not on resonance. This is the reason why some characteristics differ from those of coil filters. 3.1 Feedthrough signals

Surface acoustic wave TV IF filters have a basic delay of approx. 1 s. If unfavorable circuitry has been selected, it is quite possible for direct electrical feedthrough to be exhibited as a preecho. It is therefore advisable to terminate the filter asymmetrically at its input and symmetrically at its output. Moreover, the input and output circuitry should be appropriately spaced; long filter leads should also be avoided. 3.2 Triple-transit echo (TTE)

The triple-transit echo is an interfering signal typical of surface acoustic wave TV IF filters: the surface acoustic wave from the input transducer is reflected by the output transducer, returns to the input transducer where it is again reflected, and appears as an echo signal at the output with 3-times the basic delay. In principle, this signal is always present; however its level is not a filter constant, but is a function of the insertion loss, i.e. of internal filter attenuation and the source and load impedances. In practice, it is important to suppress the triple-transit echo at the input by low source impedance. The triple-transit echo virtually does not occur in filters designed for high-impedance loads (e.g. G1962M); if the filter is connected as specified, the TTE signal is prevented by an internal reflection compensation in the output transducer. In filters designed for low-impedance loads the TTE is suppressed by approximately double the insertion attenuation of the filter. 3.3 Reflections (spurious signals)

A transducer emits surface acoustic waves in both directions. The waves impinging on the substrate edge and reflected there can appear as echo signals. For this reason, the substrate edges are provided with an attenuator which absorbs the surface acoustic waves. In this way, reflections are reduced to a non-critical level. 3.4 Pulse response

The interfering effects mentioned above feedthrough, triple-transit echo and reflections are echo signals and are therefore in the time domain. During the design stage, such interfering effects will be calculated and kept as small as possible. In order to guarantee excellent picture and sound quality it is therefore important to record the time-domain performance, the so-called pulse response (see 4.3) in production. In the frequency domain such echos cause a ripple in the pass band of the filter. The ripple frequency is proportional to the distance in time and the ripple amplitude is proportional to the amplitude of the echo signal.

General Technical Information

3.5

Frequency response

The frequency response complies with the relevant standard or with customer-specific requirements. It can be adjusted to the user's applications, if permitted by the technology, state of the art and chip size. On account of the finite length of the transducers, which corresponds to a time-limited pulse response, the steepness of slope is limited. Since SAW filters consist of periodic finger structures, the interdigital transducers, these are also active at the harmonics of the basic frequency. However, not all harmonic waves are excited. With G 1962 M, for example, every fourth harmonic wave is excited. 3.6 Group delay of TV IF filters

The average group delay complies with the relevant standard or customer-specific requirements and is characterized in the data sheets as follows: e.g. standard B/G (G 1968 M) Group delay Reference frequency Maximum sag Color carrier 38,90 MHz 36,90 MHz 34,47 MHz

90 ns 165 ns

The typical value of the group delay ripple in the pass band is specified for filters with constant group delay. The group delay ripple depends on the echo signals, being proportional to amplitude and delay of the echo signals. Despite small amplitude and low signal power, distant echo signals may therefore lead to a considerable high-frequency group delay ripple without causing any critical phase shifts. Thus a sinusoidal group delay ripple of 100 ns peak-to-peak and a period of 800 kHz ( 1,25 s echo delay) results in a phase shift of only 2. Several non-critical reflections e.g. of 50 dB, in contrast, may add up to a conspicious group delay ripple of 50 ns. For this reason, specification of the group delay ripple for SAW filters with system-related, distant echo signals is only sensible when a frequency aperture is given. An aperture of 50 kHz is assumed for the group delay diagrams included in the data sheets. 3.7 Filter impedances

The input and output impedances of a SAW filter comprise the transducer's basic capacitance, the electrical image of the acoustic wave emission and the influence of the reflection of the waves from other transducers, which cause a ripple. The transducer impedances are therefore strongly frequency-dependent and, in conjunction with the terminating impedances, can influence the frequency response of the filter. Heavy capacitive loading at the output can, for example, produce slopes in the transfer function. Therefore, the specified terminating impedance for which the filter was designed should be used.

General Technical Information

The effects of different drive impedances (30 to 1 k) on the pulse response are shown below, using G 1968 M as an example.

Figure 5 2T/step signal behavior 32 Siemens Matsushita Components

General Technical Information

The response shown in Figure 5 is typical of many TV IF SAW filters. If the drive impedance is too high, 2T signals and rising edges become fuzzy, and the triple-transit also becomes noticeable (2,3 s after the main pulse). From about 100 the picture is perfect; a further reduction in drive impedance yields no improvement. We therefore recommend selecting drive impedances for TV IF filters as described in section 5.2. When driver stages with considerably different impedances are used (e.g. > 200 ), it should be checked which filter types are capable of producing the desired results. 3.8 Temperature coefficient of frequency

The temperature coefficient of frequency of a SAW filter is governed by the substrate material or crystal cut. With the lithium niobate Y/Z cut (standard cut), it is 94 ppm/K, and with the 128 Y/X cut (rotated cut) it is 72 ppm/K. The temperature coefficient causes the filter curve to shift towards lower frequencies as the temperature rises. For operation within a TV set, therefore, a frequency variation of the order of 50 kHz will be produced, compared to the frequency at room temperature. With the lithium tantalate 36 Y/X cut (rotated cut) it is 30 ppm/K and with the X/112 Y it is 18 ppm/K. 4 4.1 Testing Final measurements

SAW filters are subject to a 100 % final test in specially developed automatic measuring instruments. The RF section of this automatic measuring instrument consists of a network analyzer and a test jig. A computer controls all the data of the filters and determines a set of measured values in the frequency domain and in the time domain that guarantees characteristics which have not been measured directly, as, for example, the 2T response. Thus, minimum measuring time and maximum selectivity are favorably combined in this final measuring process.

Figure 6 Computer-controlled test station 4.2 Measurement results in the frequency range (e.g. TV IF filter for B/G standard)

Insertion attenuation at 37,40 MHz The attenuation value of the filter at 37,40 MHz is determined in the test circuit (see Figure 10). For this purpose a capacitive short circuit is placed between the outer connections (pins 1 and 5) and the inner connections (pins 2 and 4) instead of the filter; the insertion attenuation of the filter is given relative of the transmitted signal.

Minimum, maximum and typical values

On account of unavoidable variations in the materials and the process, all measured values show certain scatters that often follow a standard distribution. The minimum and maximum values given in the data book correspond to the measurement limits of the final measurements allowing for uncertainties and which themselves take into account any scatter. The typical values specified correspond to the 50-%-points in the cumulative distribution of the corresponding measurement values. For normal (symmetrical) distributions of measurement values (e.g. in the case of picture carriers, color carriers, sound carriers), the typical value equals the arithmetic mean. In the case of asymmetrically distributed values (e.g. for traps, upper/lower sidelobe), the typical value is generally somewhat smaller than the arithmetic mean. The values given in the data book have each been determined from a large number of filters. These mean values may, however, also be subject to certain variations. 4.4 Pulse response (time-domain measurement)

In order to measure the pulse response, a burst is applied to the filter input and the output voltage is assessed according to the following diagram. Figure 7 shows the schematic envelope curve of the RF output voltage (oscilloscope trace).

Test set-up for TV IF filters

The circuit shown in Figure 8 allows the pulse response to be measured. In order to obtain the required dynamic range of 70 dB ... 80 dB, the measuring instrument consists of two electronic mixers. Figure 9 shows the burst used: the half pulse width t hw = 250 ns is matched to the filter bandwidth. The exact slope of the pulse is non-critical. The carrier frequency of the pulse is the frequency for which the rated insertion attenuation is specified.

4.4.2

Method of computation

In final measurements, a computation process equivalent to one of the methods described above is used to evaluate the transfer function of the filter (measurement values in the frequency range), which is measured by a vectorial network analyzer. For this the complex transfer function is multiplied by the spectrum of the burst and transformed into the time domain by means of a Fourier transform. The amplitude of the transformed signal is evaluated. 4.5 Test circuits

For the automatic measuring instrument mentioned in 4.1, special test circuits were designed for TV IF filters; all data sheet information relates to these circuits. Different circuits are used for SIP-5 and DIP-10 filters (Figure 10 and 11). In both cases, wideband drivers with an output impedance of 50 were used. Filters of all standards can thus be driven without switching or adjustment. Postamplifiers provide symmetrical filter termination. The test jigs have a common-mode rejection of 30 dB at up to 80 MHz; the frequency response is negligible, and the gain is set to 26 dB. The test jigs are thus fully interchangeable. For all other types of SAW filter, test jigs are used which ensure 50 drive and load impedance to the SAW filter or the combination SAW filter and matching network respectively.

TV test signals

To check the transmission quality of a TV system, there is a series of special test signals, which in part are continually transmitted by the transmitter in certain lines external to the actual picture. These test signals enable detailed and realistic conclusions to be drawn without special measuring equipment. To assess a SAW filter, two signals are of particular interest: the 2T signal (also cos2 2T or sin2 2T pulse) and the step signal. On the screen the 2T signal corresponds to a vertical white raster line. It approximates a sin2shaped pulse with a duration (= half-value width) of 2T = 1/fc , where f c is the upper rated cutoff frequency of the video band. For the B/G standard, f c = 5 MHz, thus resulting in 2T = 200 ns. Such a signal has a frequency spectrum lying mainly below f c. Clearly stated, the 2T pulse is the shortest signal that can still be processed by the system without distortion. The oscilloscope picture of the 2T signal, e.g. at the video output of the IF stage, enables the following conclusions to be drawn: If the amplitude of the 2T signal is too high or too low, this points to amplitude errors; e.g. a tilt in the pass band of the SAW. Unsymmetrical overshoot in front of or behind the 2T signal arises through group delay errors (long wavelength errors, e.g. too little sag). Echo signals after the 2T signal point to poor reflection attenuation, e.g. of the triple-transit echo. Naturally, these errors need not have been caused by the SAW filter. Unfavorable terminating filter impedances, detuned demodulator circuits, transmission errors from previous circuits and amplifiers, as well as power echos can cause the same effects.

General Technical Information

In the simulated 2T signal shown in Figure 12, the measured transfer function is demodulated whilst taking into account the group delay predistortion taken as the basis, by conjugating the transfer function at the Nyquist point, complex mirroring it and summing it. The video frequency response is now obtained, which is multiplied by the spectrum of the 2T pulse; the result is transformed into the time domain. The real component of the transformed signal is the 2T pulse response of the filter. A figure of merit for the 2T signal is obtained from the K diagram, a tolerance diagram which is based on investigations of the interference effect of various transmission errors. Figure 14 shows the general K tolerance scheme for a 2T signal (time axis applies to the B/G standard).

Drawing corresponds to

Figure 14 K tolerance diagram S + M TV IF SAW filters comply with the K = 2 % diagram On the screen the step signal corresponds to a wide white bar at the left-hand edge. Mathematically speaking, it is the integral of the 2T signal; in principle, it therefore contains no additional information on the SAW filter. The different representation is often useful in assessing the interference effect of an error in the transmission system (see 3.7). In general, the following applies: the 2T signal is more suited for assessing a SAW filter, because it responds in a wide band to transmission errors in the pass band region. In addition, it reacts less noticeably to linearity errors in the IF IC and to envelope-curve effects in demodulation that could falsify the step signal more intensely. If reductions in the described errors are desired, to be able to better assess the effects generated by the SAW filter, it is recommended that the modulation factor of the IF modulator be reduced to 60 %.

Application notes for TV IF SAW filters Other operating conditions

All filter data quoted in the data sheets apply to the measuring conditions described. It is possible and sometimes necessary to operate the filters under different conditions. If you have any questions please contact your regional sales office. Upon request we are pleased to provide further information material, e.g. overall amplitude and time domain response. 5.2 Matching and driver stage

A low-impedance drive source is required in order to suppress the triple-transit signal. Base resistor R1 provides the defined input impedance of 50 . To obtain a wide range of linearity, a drive current of approx. 20 mA is recommended. The gain can be adjusted by R2, not lower than 470 (e.g. 29 dB with R2 = 1,8 k). To guarantee a signal-to-intermodulation ratio of 50 dB, the input voltage VIN should not exceed 80 mV. The inductivity L compensates the input capacitances of the SAW filter input and the transistor output.

Figure 15 Tuner IF matching circuit and driver stage 5.3 Switchable video/intercarrier SAW filters for multistandard applications

The family of switchable video/intercarrier filters K 62xx K offers the possibility of switching between two filter characteristics. Figure 16 shows an example of a switching network using an unsymmetrical driver (see above): To select the first channel the transistor T1 is in off-state and diode D1 connects pin 10 and pin 1. By activating T1 pin 10 is connected to ground and the other filter characteristic is selected. These filters provide the unique advantage of an optimized frequency response for multistandard concepts using a simple and inexpensive switching network.

Figure 17 shows a proposal for a switchable audio filter for unsymmetrical input. Two different filter characteristics are available in a SIP 5 K package: To select channel 1 only diode D1 is activated, the corresponding transistor T1 is in off-state. That means that the input is connected to pin 1. Pin 2 is grounded by T2. Channel 2 can be chosen accordingly.

Application notes for resonators and resonator filters

Principle: An oscillator is an amplifier with a signal feedback from the output to the input.

Figure 18 Basic circuit diagram

To achieve oscillation it is necessary to meet the following conditions: Amplitude: Phase:

G =a +b >1 Ptot = P1 + P2 + P3 = n 360

The amplitude condition means that the total gain G in the loop is greater than 1 and the phase condition postulates a total phase shift in the oscillator loop of n 360. 6.1 6.1.1 Typical oscillation circuits Oscillators using a one-port resonator

The common base Colpitz circuit is one of the preferably used oscillating circuits for one-port resonators.

Figure 19 Colpitz with common base

General Technical Information

To achieve oscillation, the resonance frequency of the parallel resonance circuit should be near the SAW resonance frequency. Neglecting the internal transistor capacitances, the load and the PCB parasitics, the parallel resonance Fp of ( C1 serial C2) and L1 is determined by: 1 --- --- --- --- --- --- --- --- Fp = - --- --- --- --- -- --- --- --C1 C2 2 L1 --- --- --- --- --- --C 1 + C2

R1, R2 and R3 are for DC biasing. C3 matches the high collector impedance to the load impedance. The signal feedback depends on the relation of C1 and C2.
The concrete values for C1, C2 C3 and L1 must be evaluated on the board to get the desired oscillation frequency. The SMD transistor should be a high-frequency type with a transit frequency of a few GHz. Often it is possible to design the inductivity L 1 like a copper line on the PCB (without ground on the backside). So you receive an antenna. 6.1.2 Oscillators using a two-port resonator

The typical circuit for two-port resonators is the Pierce oscillator.

Figure 20 Pierce osillator The amplifier part of the oscillator is a transistor with grounded emitter. The SAW resonator is embedded between two -type tuning networks. These networks control the phase shift in the feedback loop to meet the oscillation conditions. Otherwise they match the input and output impedance of the tranistor to the desired impedance of the SAW resonator. In the tuning network the parallel capacitors Cp1, Cp2, Cp 3 and Cp4 are often substituted by the transistor's and the SAW resonator's input and output capacitors. The phase shift in the oscillating loop is controlled mainly by L s1/ Cp1 and L s2/Cp3 . C6 is for output matching and L 3 is for DC bypassing.

Application for a wireless remote control system at 433,92 MHz

Fields of application for SAW resonators are remote control systems for keyless entry, security systems and wireless telemetry. Figure 21 and Figure 22 show an AM remote control system at 433,92 MHz. The transmitter is a SAW-stabilized oscillator with a PCB antenna, where a one-port SAW resonator is designed in, using the basic circuit of Figure 19. The modulation is OOK (On Off Keying). The receiver is a superheterodyne receiver with an IF of 10,7 MHz. For preselection and rejection of the image frequency a SAW filter is designed in at the input. The local oscillator is stabilized by a SAW resonator. For the transmitter and for the receiver it is necessary to provide a good common RF ground and short connections between the RF components. It is also recommended to separate the digital part from the RF part on the PCB. Both circuits are developed for small power consumption.
