AERO4208
General Description
The Aero4208 transceiver is a complete RF transceiver for multi-band GSM, GPRS and EDGE Receive wireless communications. The receive section interfaces between the RF band-select SAW filters and the baseband subsystem. The Aero4208 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 Aero4208 provides a complete upconversion path from the baseband subsystem to the power amplifier (PA) using an offset phase-locked loop (OPLL) integrated with ST-Ericsson's patented synthesizer technology.
All sensitive components, such as VCOs, loop filters, tuning inductors, and varactors are totally integrated into a single integrated circuit. The Aero4208 transceiver includes a digitally controlled crystal oscillator (DCXO) and completely integrates the reference oscillator and varactor functionality.
