Highly integrated GSM/GPRS transceiver

23 October 2002 Telecoms, Datacoms, Wireless, IoT

Silicon Laboratories' Aero+ GSM/GPRS transceiver is a new addition to the company's 100% CMOS RF Aero transceiver product family. This is a highly integrated transceiver for multiband GSM digital cellular handsets and GPRS voice and data terminals. It has an integrated digitally controlled crystal oscillator (DCXO), eliminating the need for an expensive voltage controlled temperature compensated crystal oscillator (VC-TCXO).

The Aero+ transceiver integrates the entire frequency error compensation circuit including the reference amplifier, automatic gain control loop and varactor diode. A low-cost crystal resonator is the only required external component. It also integrates the IF SAW filter, external low noise amplifiers (LNAs), transmit and RF VCO modules and more than 60 other discrete components.

The Aero+ transceiver includes: the 32-lead micro-leadframe package (MLP) Si4200 transceiver; 20-lead MLP Si4201 baseband interface; and 32-lead MLP Si4134T RF synthesizer.
