3. TECHNICAL BRIEF 3. TECHNICAL BRIEF 3.1 General Description of RF parts The RF parts consists of a transmitter part,a receiver part,a synthesizer part,a voltage supply part,a VCTCXO part. And the main RF Chipset CX74017[U603]is a single-chip dual-band transceiver for the extended global system for mobile communication[E-GSM900MHz]/ Digital communication system[DCS1800MHz] voice and data transfer applications.
Page 15 3. TECHNICAL BRIEF A. RF Front End RF front end consists of Antenna Switch(FL405), an integrated two saw filters,(FL601),dual band LNAs integrated in transceiver. The Received RF signals(GSM 925MHz ~ 960MHz, DCS 1805MHz ~ 1880MHz) are fed into the antenna or Mobile switch. An antenna matching circuit is between the antenna and the mobile switch.
Page 16 3. TECHNICAL BRIEF B. Demodulator and baseband processing In direct conversion receiver there is only one mixer down-converting received RF signal to BB signal directly. The gain down converting mixer is 40dB at high gain mode and 22dB at low gain mode. The Rx gain setting is done in the AGC algorithm.

3. TECHNICAL BRIEF 3.3 Synthesizer Part CX74017 2V7_VTCXO 13MHz vco = (N+3.5+FN/2^22) ref/R 13MHz Fractional-N REFCLK Base Band Block Figure.3-2 Synthesizer Block diagram The CX74017 includes a fully integrated UHF VCO with an on-chip LC tank. A single sigma-delta fractional-N synthesizer can phase lock the local osillator used in both transmit and receive path to a precision frequency reference input.
Page 18: Transmitter Part
3. TECHNICAL BRIEF 3.4 Transmitter Part The Transmitter part contains CX74017 active parts, PAM and Antenna Switch. The CX74017 active part consists of a vector modulator and offset phase-locked loop block(OPLL) including down-converter, phase detector, loop filter and dual band transmit VCO which can operate at either final RF output frequency.
Page 19 3. TECHNICAL BRIEF A. IF Modulator The baseband converter(BBC) within the GSM chipset generates I and Q baseband signals for the transmit vector modulator. The modulator provides more than 40dBc of carrier and unwanted side- band rejection and produces a GMSK modulated signal. The baseband software is able to cancel out differential DC offsets in the I/Q baseband signals caused by imperfections in the D/A converters.
