Description  
The T2803 is an RF IC for low-power applications in the 2.45 GHz ISM band. The  
QFN48-packaged IC is a complete transceiver including image rejection mixer, IF  
amplifier, FM demodulator, baseband filter, RSSI, TX preamplifier, power-ramping  
generator for power amplifiers, integrated synthesizer, fully integrated VCO and Gaus-  
sian data filter for TX. No mechanical tuning is necessary in production.
