3.1 Transceiver (SI4210, U501)
The RF parts consist of a transmitter part, a receiver part, a frequency synthesizer part, a voltage
supply part, and a VCTCXO part.
The Aero I transceiver is the integrated RF front end for multi-band GSM/GPRS digital cellular
handsets and wireless data modems. The integrated solution eliminates the IF SAW filter, external low
noise amplifier (LNAs) for three bands, transmit and RF voltage controlled oscillator (VCO modules,
and other discrete components found in conventional designs.
