3.18. RF Block General Description
3.18.1. General Description : RF block 1(SG3)
The RF transceiver (PMB 6272 SMARTi-PM) is an integrated single chip, quad-band transceiver for
GSM850/GSM900/GSM1800/GSM1900 designed for voice and data transfer applications. The
transceiver provides an analog I/Q baseband interface and consists of a direct conversion receiver and a
quad-band polar transmitter for GSM and EDGE with integrated PGA functionality. Further on a
completely integrated SD-synthesizer with HSCSD and GPRS/EDGE capability, a digitally controlled
reference oscillator with three outputs, a fully integrated quad-band RF oscillator and a three wire bus
interface with all necessary control circuits complete the transceiver.
