3-1 RECEIVER CIRCUITS
3-1-1 RF SWITCHING CIRCUIT (MAIN UNIT)
The IC-R75 has two antenna connectors. RF signals enter either the [50 ANT.] or [450 ANT.] connector. RF signals from the [50 ANT.] connector are applied to the antenna switching circuit (RL121), and then pass through the low-pass filter (L131, L132, C131C136). RF signals from the [450 ANT.] connector are passed through the L101 to exchange the impeadance value, and are then applied to the antenna switching circuit (RL121). The signals are applied to the low-pass filter (L131, L132, C131C136). Each RF signals from the [50 ANT.] connector or [450 ANT.] connector are chosen by the antenna switching circuit (RL121). (1) Below 1.6 MHz The signals are applied to the low-pass filter consisting of C170C175, L171L173 via the limitter circuit (D141, D142). A diode is removed at the entrance of the low-pass filter. This device prevents the diode from causing distortion when receiving very strong signals. A switching diode (D172) is turned on when the "B0" line is "HIGH". (2) Above 1.6 MHz The signals are applied to the high-pass filter consisting of C161C163, L161L164. This filter suppresses strong signals below 1.6 MHz such as broadcasting stations. The filtered signal between 1.6 MHz and 2.0 MHz are applied to the low-pass filter (C182C187, L182, L183) via the switching diode (D181). The switching diodes (D181, D182) are turned ON when the "B1" line is "HIGH". The filtered signals above 2.0 MHz are applied to one of 8 bandpass filters depending on the receive frequencies. After passing through a bandpass or low-pass filter, the signals are applied to the pre-amplifier circuit (Q381, Q382, IC391). (3) FILTER SWITCHING CIRCUIT The RF bandpass filter corresponds to the BPF switching voltage (B0B9) based on the CPU via the shifit registor (IC551, IC552) and driver (IC561, IC562). The switching voltage of the BPF exit ot improve multi-signal and strong signal characteristics.
3-1-2 RF FILTER CIRCUIT (MAIN UNIT)
The filtered signals are applied to the RX attenuator switching circuit (RL141). Either the signals bypass or pass through the attenuator circuit. The signals are attenuated at 20 dB when passing through the attenuators. The attenuator system excludes non-linear components between an antenna connector and an attenuator to prevent strong signals from causing distortion. The signals are then applied to the RF filters. The MAIN UNIT has 8 RF bandpass fileters for signals above 2.0 MHz and 2 low-pass filters for signals below 2.0 MHz.

3-1-3 PRE-AMPLIFIER CIRCUIT (MAIN UNIT)
The pre-amplifier circuit uses low noise junction FETs (Q381, Q382) or wideband amplifier (IC391) to provide gain over a wide frequency range. When the [P.AMP] switch is turned "PREAMP 1", the signals from the RF filter are amplified by the junction FETs preamplifier circuit (Q381, Q382). When the [P.AMP] switch is turned "PREAMP 2", the signals from the RF filter are amplified by the wideband pre-amplifier circuit (IC391). When the [P.AMP] switch is turned "PREAMP OFF", the signals from the RF filter bypass the pre-amplifiers through D371 and D372. The amplified or bypassed signals are applied to the 1st mixer circuit (Q441, Q442) via the low-pass filter (L431, L432 and C431CC436). The low-pass filter attenuates at 50 MHz to suppress image frequency.
The 69.0415129.0115 MHz 1st LO signal is applied to an LO amplifier (Q411) from the PLL unit via J411, and then passes through the low-pass filter (L421, L422, C422C425).

3-1-6 NOISE BLANKER CIRCUITS (MAIN UNIT)
The IC-R75 uses a trigger noise blanker circuit which removes pulse-type noise signals at the noise blanker gate (D711D714). The 2nd IF signal passes through the crystal bandpass filter (FI701) to suppress unwanted signals. A portion of the output signal is applied to a noise amplifier circuit (IC731, Q731, Q733) and detected at a noise detector circuit (D731). The detected voltage is applied to a noise blanker gate control circuit (Q735Q737, D732). The threshold level of the noise blanker gate control circuit (Q735Q737, D732) is set at 1.0 V on SSB mode (In case of AM mode, is set at 1.6 V). When the detected voltage exceeds the threshold level, Q737 outputs a blanking signal to activate the noise blanker gate (D711D714). A portion of the detected voltage is applied to the noise blanker AGC circuit (Q732, Q734). The noise components are fed back to the noise amplifier (IC731). The time constant of the noise blanker AGC circuit is determined by R737, R744 and C739. This AGC circuit does not operate to detect pulse-type noise. When the operating frequency or mode is changed, the "UNLC" signal is applied to the noise blanker gate control circuit (D732). The noise blanker gate prevents PLL click noise.
3-1-8 BFO CIRCUIT (PLL UNIT)
The BFO (Beat Frequency Oscillator) circuit consists of Q1, X1, Q201 and IC 201 on PLL unit. The oscillator provides a beat frequency signal to the SSB demodulator circuit (MAIN UNIT; IC1101) for demodulating the 3rd IF signal into an AF signal. The 30 MHz signal is oscillated at Q1 and X1 for the system clock signal of the DDS IC (IC201). The oscillated signal is amplified at Q201 and is applied to the DDC IC (IC201, pin 7) to produce the 455 kHz BFO signal. The 455 kHz signal passes through the low-pass filter (L201, L202, C202C207) via the D/A converter, and is then mixed with the 3rd IF signal at the SSB demodulator circuit (MAIN unit; IC1101).

(3) AM DEMODULATOR CIRCUIT The AM demodulater circuit (IC2001) has the envelope detect function and the synchronous detect function. An AM detector (IC2001) demodulates the AM signal into an AF signal. The 3rd IF signal from the IF amplifier (Q911) is amplified at the buffer amplifier (Q1031), and is then applied to the AM demodulater circuit (IC2001)to demodulate the 3rd IF signal into the AM AF signal. The AF signal which is the AM envelope detect the AF signal or the AM synchronous detect AF signal passes through the AF input mode selector switch (IC1201).
The AGC mode is selected by the receiver mode or AGC swtich on the front panel using the delay control circuit (Q1064Q1066). The MDAT signal from the CPU (LOGIC board; IC101, pin 21) is applied to the shift resistor (IC1601, pin 2) to produce the AGSS and the AGFS signals. The AGSS signal is applied to the Q1064, the AGFS signal is applied to the Q1065, the AGRS signal from the CPU (LOGIC unit; IC101, pin 80) is applied to the Q1066 to control the delay control circuit. The AGRS signal resets the AGC circuit when IC-R75 is working the memory scaning. When the AGC switch is selected "OFF", the Q1061 do not supply the voltage to the AGC amplifier (Q1063) via the "AGOS" line, determining the time constant to deactivate the AGC circuit. A portion of the AGC bias voltage is amplified at the S-Meter amplifier circuit (IC1211C, D831), and then applied to the CPU (LOGIC unit; IC101, pin 95) via the "SML" line. Thus, the CPU controls S-Meter display.

The "SML" signal is applied to the CPU (LOGIC unit; IC101, pin 91) from the meter amplifier circuit (IC1211C, D831). The CPU compares "SML" signal with the level of SQL volume on the VR BOARD to control the "SQL" signal. The CPU is output the "SQLS" signal from pin 81, and then applied to the AF selector circuit (MAIN unit; IC1201, pin 6) which has also the squelch gate circuit.
3-1-11 AF AMPLIFIER CIRCUIT (MAIN AND FRONT UNITS)
The AF signal output is passed though the low-pass filter (IC1211) to suppress unwanted signals. The filtered signal is mixed with "BEEP" signal at the AF level variable circuit (MAIN unit; IC1251), and is then applied to the AF amplifier circuit and the AF level variable circuit (IC1251). The AF level variable circuit controls the AF level by the "AF GAIN" (R141) on the VR BOARD. The AF signal is applied to the AF mute circuit to suppress the noise when "AF GAIN" (R141) level is minimum, and is then power-amplified at IC1291 on the MAIN unit to drive the speaker. The one of the AF amplified signal is output "AAFO" signal to record the AF signal to the AF recording jack (PLL unit; J3).
3-2 PLL CIRCUITS
3-2-1 GENERAL DESCRIPTION

The IC-R75 uses a DDS (Direct Digital synthesizer) system. The DDS system provides rapid lockup time and high quality frequency oscillation.
3-1-12 AGC AND S-METER CIRCUITS (MAIN UNIT)
The AGC (Automatic Gain Control) circuit reduces signal fading and keep the audio output level constant. The receiver gain is determined by voltage on the AGC line (Q1063, collector). When strong signals are received, the AGC circuit decreases the voltage on this line. The 3rd IF signal is amplified at the IF amplifier (Q911). A portion of the 3rd IF signal is applied to the buffer amplifier (Q1031) to convert the impedance. The amplified IF signal is detected at the AGC detector (D1061) via the C1061, and enters the base of the AGC amplifier (Q1063) to control the voltage on the AGC line.
