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.
