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.
