2. Circuit Description
2-1. SGH-Z150 RF Circuit Description
- Antenna Switch Module (U600) The antenna switch module allows multiple operating bands and modes to share the same antenna. A common antenna connects to one of seven paths: 1) UMTS-2100 Rx/Tx, 2) EGSM-900 Rx, 3) EGSM-900 Tx, 4) DCS-1800 Rx, and 5) DCS-1800 Tx. 6) PCS-1900 Tx, 7) PCS-1900 Rx, UMTS operation requires simultaneous reception and transmission. - Filter To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band. · · · · · GSM Rx FILTER (F600) For filtering the frequency band between 925 and 960 MHz. DCS Rx FILTER (F601) For filtering the frequency band between 1805 and 1880 MHz. PCS Rx FILTER (F602) For filtering the frequency band between 1930 and 1990 MHz. WCDMA Rx FILTER (F700) For filtering the frequency band between 2110 and 2170 MHz. WCDMA Tx FILTER (F701) For filtering the frequency band between 1920 and 1980 MHz.
- VCTCXO (TCX700) To generate the 19.2MHz reference clock to drive the logic and RF. - Duplexer (F702) A duplexer splits a single operating band into receive and transmit paths. - WCDMA PAM (PAM702) This is a key component in the transmitter chain and must complement the RTR6200 IC precisely; jointly they dominate the UMTS transmitter performance characteristics. Parameters such as gain, output power level, ACLR, harmonics, Rx-band noise, and power supply current are critical. - GSM/DCS/PCS PAM (PAM602) The PAM is a key component in any transmitter chain and must complement the rest of the transmitter precisely. For GSM, DCS, PCS operation, the closed-loop transmit power control functions add even more requirements relative to the UMTS PA. In addition to gain control and switching requirements, the usual RF parameters such as gain, output power level, several output spectrum requirements, and power supply current are critical. - GSM/DCS/PCS Dual Tx VCO (VCO600) The dual Tx VCO outputs, one for EGSM and one for DCS/PCS, drive a resistive network that splits the active signal into two signals: 1) the input to the active PAM which is the low loss path, and 2) the OPLL feedback signal. - RFR6250 (U701) The RFR6250 provides the Zero-IF receiver signal path, from RF to analog baseband, for UMTS-2100 applications. The RFR6250 includes an LNA circuit optimized for UMTS-2100 operation and a VCO which generate UMTS Rx LO signal. The RFR6250 accepts its UMTS input signal from the handset RF front-end design. The UMTS input is configured differentially to optimize second-order inter-modulation and common mode rejection performance, and implements MSM-controlled gain adjustments to extend the receiver dynamic range. 2-1

2-2. SGH-Z150 Baseband Circuit description
2-2-1. PM6650-2
- Power Management Ten low-dropout regulators designed specifically for GSM applications power the terminal and help ensure optimal system performance and long battery life. It provides seven LDO support for 1.375V, 1.8V, 2.6V, 2.85V, 3.0V, 3.3V while a self-resetting, electronically fused switch supplies power to external accessories. Ancillary support functions, such as RTC module and RTC charger, Clock Buffer, aid in reducing both board area and system complexity. SBI BUS serial interface provides access to control and configuration registers. This interface gives full control of the MSM6250A and enables system designers to maximize both standby and talk times. Supervisory functions. including a reset generator, an input voltage monitor, and a ADC Conertte support reliable system design. These functions work together to ensure proper system behavior during start-up or in the event of a fault condition(low microprocessor voltage, insufficient battery energy, or excessive die temperature). - TCXO Controller and Buffers The PM6650-2 IC includes circuits for controlling the TCXO warm-up and buffering its signal for distribution throughout the handset. Performance specifications are presented below.
2-2-2. Connector
- LCD Connector LCD has 1.9", 176x220 resolution (color 260K TFT LCD). Chip select signals in MSM6250A, MAIN_LCD_CS can enable main LCD and MAIN_LCD_BACKLIGHT enables white LED of main LCD. nRESET_LCD signal initiates the reset process of the main LCD. - Key This is consisted of key interface pins among MSM6250A IC, KYPD_N(9,11,13,15,17) and KEYSENSE(0:3). These signals compose the matrix. Result of matrix informs the key status to key interface in the MSM6250A. Power on/off key(PHONE_ON) is separated from the matrix. The key LED use the "VREG_KEY_LED" supply voltage. - ESD Filter This system uses the ESD filter(GMF05LC) and ESD-EMI filter(ICVE21184E070R101FR) to protect noise from CONNECTORs and part. - IF connetor and EAR-JACK It is 20-pin connector and is compatibly used for IF connector or EAR-JACK. They are designed to use VBATT, USB_VBUS, VEXT_5V, JTAG_SEL, TDO_TX, TDI_RX, JIG_ON, USB_D+, USB_D-, EAR_MICP, EAR_MIC_N, TRST_EARR, TMS_EAR, TCK_EARSW, RTCK_JACKINT, ADC_BOOTSW.

The synthesizer section adopts "stereophonic hybrid synthesizer system" that are given advantages of both FM synthesizers and Wave Table synthesizers to allow simultaneous generation of up to 32 FM voices and 32 Wave Table voices. Furthermore, YMU765 has a built-in hardware sequencer that helps to realize complex play without heavily loading the host CPU. And this device also has a built-in circuit for controlling vibrators and LEDs synchronizing with play of music. The consumed electric current can be stopped to the minimum by power down mode when not operating. The hardware sequence built in this device allows playing of the complex music without giving excessive load to the CPU of the portable telephones. Moreover, the registers of the FM synthesizer can be operated directly for real time sound generation, allowing, for example, utilization of various sound effects when using the game software installed in the portable telephone.
