A common antenna connects to one of five paths: ) UMTS-200 Rx/Tx, 2) EGSM-900 Rx, ) EGSM-900 Tx, 4) DCS-800 Rx, and 5) DCS-800 Tx. 6) PCS-900 Tx, 7) PCS-900 Rx, UMTS operation requires simultaneous reception and transmission. 2. Filter To convert Electromagnetic Field Wave to Acoustic Wave and then pass the specific frequency band. - GSM Rx FILTER (F702) For filtering the frequency band between 925 ~ 960 MHz. - DCS Rx FILTER (F70) For filtering the frequency band 805 and 880 MHz. - PCS Rx FILTER (F700) For filtering the frequency band 90 and 990 MHz. - WCDMA Rx FILTER (F800) For filtering the frequency band 20 and 270 MHz. - WCDMA Tx FILTER (F802) For filtering the frequency band 920 and 980 MHz.. VCTCXO To generate the 9.2MHz reference clock to drive the logic and RF. 4. Duplexer (TCX800) A duplexer splits a single operating band into receive and transmit paths. 5. UMTS PAM (U800) This is a key component in the transmitter chain and must complement the RTR6250 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. 6. GSM/DCS/PCS PAM (U70) 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. 7. GSM/DCS/PCS l Tx VCO (OSC700) The Tx VCO outputs for EGSM, DCS, PCS drive a resistive network that splits the active signal into two signals: ) the input to the active PAM this is the low loss path, and 2) the OPLL feedback signal. 8. RF VCO The single-band UHF VCO is a key component within its phase-locked loop; VCO performance directly impacts PLL and transceiver performance. UMTS Rx LO signal is generated from this VCO's output. 2-

6 Circuit Description 9. RFR6250 (U80) The RFR6250 provides the Zero-IF receiver signal path, from RF to analog baseband, for UMTS-200 applications.
