1. Description

T2801

The T2801 is an RF IC for low-power DECT applications. 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, TX filter and modulation compensation

circuit for advanced closed-loop modulation concept. No mechanical tuning is neces-

sary in production.
