2. Circuit Description 2-1. SGH-Z140 RF Circuit Description - Antenna Switch Module (U103) 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 (F100) → For filtering the frequency band between 925 ~ 960 MHz. ·

DCS Rx FILTER (F101) → For filtering the frequency band 1805 and 1880 MHz.

·

PCS Rx FILTER (F102) → For filtering the frequency band 1930 and 1990 MHz.

·

WCDMA Rx FILTER (F200) → For filtering the frequency band 2110 and 2170 MHz.

·

WCDMA Tx FILTER (F201) → For filtering the frequency band 1920 and 1980 MHz.

- VCTCXO (OSC200) To generate the 19.2MHz reference clock to drive the logic and RF. - Duplexer (F203) A duplexer splits a single operating band into receive and transmit paths. - WCDMA PAM (U201) 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 PAM (U102) 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 Dual Tx VCO (OSC101) The dual Tx VCO outputs, one for EGSM and one for DCS, drive a resistive network that splits the active signal into two signals: 1) the input to the active PAM – this is the low loss path, and 2) the OPLL feedback signal. - Dual VCO (OSC201) The dual-band UHF VCO is a key component within its phase-locked loop; VCO performance directly impacts PLL and transceiver performance. GSM/DCS Rx/Tx LO & UMTS Rx LO signal is generated from this dual VCO's output.

Circuit Description

- RFL6200 (U200) The RFL6200 includes an LNA circuit optimized for UMTS-2100 operation. The LNA is separated from all other receive functions contained within the RFR6200 receiver IC to improve mixer LO to RF isolation – a critical parameter in the Zero-IF architecture. - RFR6200 (U203) The RFR6200 provides the Zero-IF receiver signal path, from RF to analog baseband, for UMTS-2100 applications. The RFR6200 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. - RTR6250 (U101) The RTR6250 supports multi-band, multi-mode phones with two receiver signal paths and three transmitter signal paths: 1) Receiver paths - EGSM-900 - DCS-1800 - PCS-1900 2) Transmitter paths - EGSM-900 (using OPLL technique) - DCS-1800 (using OPLL technique) - PCS-1900 - UMTS-2100 Numerous secondary functions are integrated on-chip as well: 3) Phase-locked loop circuits - PLL#1 and an on-chip VCO supports UMTS Tx - PLL#2 and an external VCO supports EGSM Rx and Tx, DCS Rx and Tx, DCS Rx and Tx and UMTS Rx 4) Transceiver LO generation and distribution circuits - EGSM-900 Rx and Tx - DCS-1800 Rx and Tx - PCS-1900 Rx and Tx - UMTS-2100 Tx

Circuit Description

2-2. Baseband Circuit description of SGH-Z140 2-2-1. PM6650 - 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 MSM6250 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 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 is consisted of main LCD(color 260K TFT LCD) and small LCD(color 65K LCD). Main LCD has 1.8", 176x220 resolution and sub LCD has 1.07", 96x96 resolution. Sub LCD uses STR to improve reflection performance. Chip select signals in MSM6250, MLCD_CS_N can enable main LCD and SLCD_CS_N can enable small LCD. MLCD_BL_EN enables white LED of main LCD. MLCD_RESET signal initiates the reset process of the main LCD. SLCD_RESET signal initiates the Reset process of the small LCD. - Key This is consisted of key interface pins among U301, KEY_N(0:4). These signals compose the matrix. Result of matrix informs the key status to key interface in the U301. Power on/off key is seperated from the matrix. The key LED use the "VREG_KEY_LED" supply voltage. "HALL_SW" informs the status of folder (open or closed) to the. - EMI ESD Filter This system uses the EMI ESD filter, GMF05LC to protect noise from IF CONNECTOR part. - IF connetor It is 24-pin connector. They are designed to use VBATT, VF, MSM_TDI, MSM_TDO, MSM_TCK, MSM_TMS, MSM_TRST, MSM_RTCK, RFR, CTS, JIG_ON, USB_VBUS, RXD, TXD, BOOT_SW and GND. They connected to power supply IC, microprocessor and signal processor IC.
