Circuit Description 1. SGH-X640 RF Circuit Description 1) RX PART 1. ASM(U103) → Switching Tx, Rx path for GSM900, DCS1800, PCS1900 by logic controlling. 2. ASM Control Logic (U103) → Truth Table VC1 VC2 VC3 GSM Tx Mode H L L DCS Tx Mode L H L PCS Tx Mode H L L GSM Rx Mode L L L DCS Rx Mode L L L PCS Rx Mode L L H 3. FILTER To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band. - GSM FILTER (F100) → For filtering the frequency band between 925 and 960 MHz - DCS FILTER (F102) → For filtering the frequency band between 1805 and 1880 MHz. - PCS FILTER (F101) → For filtering the frequency band between 1930 and 1990 MHz. 4. VC-TCXO (OSC100) This module generates the 26MHz reference clock to drive the logic and RF. After division by two a reference clock of 13MHz is supplied to the other parts of the system through the pin CLKOUT. After additional process, the reference clock applies to the U100 Rx IQ demodulator and Tx IQ modulator. And then, the oscillator is controlled by serial data to select channel and use fast lock mode for GPRS high class operation. 5. Transceiver (U100) The receiver front-end which amplifies the GSM, DCS aerial signal, converts the chosen channel down to a low IF signal of 100 kHz. The first stages are symmetrical low noise amplifiers (LNAs). The LNAs are followed by an IQ down mixer. It consists of two mixers in parallel but driven by quadrature out of phase LO signals. The In phase (I) and Quadrature phase (Q) IF signals are low pass filtered to provide protection from high frequency offset interferes. The low IF I and Q signals are then fed into the channel filter. The front-end low IF I and Q outputs enter the integrated bandpass channel filter with provision for five 8 dB gain steps in front of the filter. 2) TX PART I and Q baseband signals are applied to the IQ modulator that shifts the modulation spectrum up to the transmit IF. It is designed for low harmonic distortion, low carrier leakage and high image rejection to keep the phase error as small as possible. 2-1 SAMSUNG Proprietary-Contents may change without notice This Document can not be used without Samsung's authorization Circuit Description The modulator is loaded at its IF output by an integrated low pass filter that suppress unwanted spurs prior to get into the phase detector. The clock drive is generated by division of the RFLO signal provided for the transmit offset mixer. Baseband IQ signal fed into offset PLL, this function is included inside of U100 chip. OSC101 chip generates modulator signal which power level is about 6.5dBm and fed into Power Amplifier(U102). The PA output power and power ramping are well controlled by Auto Power Control circuit. We use offset PLL below table. Modulation Spectrum 200kHz offset 30 kHz bandwidth GSM -35dBc DCS -35dBc 400kHz offset 30 kHz bandwidth GSM -66dBc DCS -65dBc 600kHz ~ 1.8MHz offset 30 kHz bandwidth GSM -75dBc DCS -68dBc 2. Baseband Circuit description of SGH-X640 1. PCF50601 1.1.
