V I T EL COM M OB I L E T ECH N OL OGY S.A . 4.2 RF part Description The RF part consists of power part, synthesizing part, transmission and reception part. 4.2.1 Description of Frequency Synthesizer Circuit The UHF band frequency synthesizer is composed of an indirect frequency synthesizer, Phase Locked Loop (PLL IC, U2), VCO(U102) with the center frequency of 966.88MHz for CDMA mode and Loop Filter.
V I T EL COM M OB I L E T ECH N OL OGY S.A . dividing the Tx IF VCO output frequency by two. 4.2.2 Description of Rx Part Circuit Cellular Receiver covers the RF frequency band of 869 ~ 894 MHz and the IF frequency of 85.38MHz. The RF signal received is sent out to the Receiver MMIC/ LNA(U106) via a duplexer(F100) for amplification and then, is sent out to the Receiver MMIC/ Down mixer(U106) through Rx RF SAW filter(U107).
V I T EL COM M OB I L E T ECH N OL OGY S.A . Rx IF SAWFilter (U108) The Rx IF SAW filter(U108) protects its following stages from close-in Inter Modulation (IM) signals, provides adjacent channel selectivity, and attenuates the second image. RX_BBA (U109) Rx_BBA is divided three main parts, IF frequency processing, base-band processing, and digital interface.
V I T EL COM M OB I L E T ECH N OL OGY S.A . 4.2.3 Description of Tx Part Circuit The 8 bit digital signal fed into TX_BBA(U112) passes through DAC using TXCLK and TXCLK/ as triggers to produce base band I/Q signal. Inside the MSM(U125), each signal is sent out to the up mixer via a digital low pass filter. At the mixer, 130.38 MHz I/Q signal obtained by dividing the 260.

Figure 4.7 TX_BBA Functional Block Diagram 4.3 Logic Part Description The logic part processes the user’s commands and processes all the digital in order to operate in the phone. The logic part is made up of a keypad/ LCD, receptacle part, voice processing part, mobile station modem(MSM, U125) part, memory part(U113), and power supply part. 4.3.1 Keypad/ LCD This is used to transmit keypad signals to MSM(U125).
V I T EL COM M OB I L E T ECH N OL OGY S.A . MSM(U125) Internal Block 1) ARM Microprocessor Subsystem The MSM(U125) uses an embedded ARM7TDMI microprocessor. The ARM7TDMI microprocessor, through the system software, controls most of the functionality for the Mobile Station, including control of the external peripherals such as the keypad, LCD display, RAM and ROM/FLASH(U113) devices.
V I T EL COM M OB I L E T ECH N OL OGY S.A . This interface is specifically designed to be a quick, low pin count control protocol for Qualcomm’s TX_BBA(U112) can be configured for different operating modes and configured for minimum power consumption, extending battery life in standby mode. 8) User Interface MSM(U125) user interface comprises digital connections to the subscriber unit ringer transducer, keypad and LCD display.
