3. TECHNICAL BRIEF 3. TECHNICAL BRIEF 3.1 Transceiver (CX74017, U401) 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[U401]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 14 3. TECHNICAL BRIEF A. RF Front End RF front end consists of Antenna Switch(FL401), dual band LNAs integrated in transceiver(U401). 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. The Antenna Switch (FL401) is used to control the Rx and TX paths.
Page 15 3. TECHNICAL BRIEF C. DC offset compensation Three correction loops ensure that DC offsets, generated in the CX74017, do not overload the baseband chain at any point. After compensation, the correction voltages are held on capacitors for the duration of the receive slot(s).
Page 16 3. TECHNICAL BRIEF (2) Transmitter Part The Transmitter part contains CX74017 active parts, power amplifier module (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 17 3. TECHNICAL BRIEF B. OPLL The offset mixer down converts the feedback Tx RF signal using LO to generate a IF modulating signal. The IF signal goes via external passive bandpass filter to one port of the phase detector. The other side of the phase detector input is LO signal. The phase detector generates an error current proportional to the phase difference between the modulated signal from the offset mixer and the reference signal from the LO.

12. AUTO CALIBRATION 12. AUTO CALIBRATION 12.1 Overview AutoCal (Auto Calibration) is the PC side calibration tool that performs Rx and Tx calibration with Agilent 8960 or other equipment. AutoCal generates calibration data by communicating with phone and measuring equipment and writes it into calibration data block of flash memory in GSM phone. There are three steps for automatic gain control (AGC) for Rx, automatic power control (APC) for Tx, and ADC control for monitoring battery voltage.
