Description
The Aero I transceiver is a complete RF front end for multi-band GSM
and GPRS wireless communications. The transmit section interfaces
between the baseband processor and the power amplifier. The receive
section interfaces between the RF band-select SAW filters and the
baseband processor. All sensitive components, such as RF/IF VCOs,
loop filters, and tuning inductors, are completely integrated into a single
compact package.
