Aero IIe Transceiver for GSM, GPRS, and EDGE
Features
- 5 x 6 mm 36-pin QFN - Highly integrated transceiver supports both GMSK and 8-PSK modulation - Unique dual-transmitter architecture - Integrated frequency synthesizer including all VCOs
and loop filters
Description
The Aero® IIe transceiver is a complete RF front end for multi-band GSM, GPRS, and EDGE wireless communications. The receive section interfaces between the RF band-select SAW filters and the baseband processor. The transmit section interfaces between the baseband processor and the power amplifier and uses a unique dual-transmitter architecture for EDGE. In GMSK mode, the offset phase locked loop (OPLL) is modulated by the I and Q signals.
