com Si4209 Si4209 Transceiver for GSM and GPRS Description The Si4209 transceiver is a complete RF front end for dual-band GSM and GPRS wireless communications.
The receive section interfaces between the RF band-select SAW filters and the baseband subsystem.
The Si4209 receiver leverages a proven digital low-IF architecture and enables a universal baseband interface without the need for complex dc offset compensation.
The transmit section of Si4209 provides a complete upconversion path from the baseband subsystem to the power amplifier (PA) using an offset phase-locked loop (OPLL) integrated with Silicon Laboratories’ patented synthesizer technology.
All sensitive components...
