TRC105

300-510 MHz RF Transceiver

RF Monolithics, Inc 

Product Overview

TRC105 is a single chip, multi-channel, low power UHF transceiver. It is

designed for low cost, high volume, two-way short range wireless applica-

tions in the 300 to 510 MHz frequency range. The TRC105 is FCC & ETSI

certifiable. All critical RF and base-band functions are integrated in the

TRC105, minimizing external component count and simplifying and speeding

design-ins. A microcontroller, RF SAW filter, 12.8 MHz crystal and a few pas-

sive components are all that is needed to create a complete, robust radio

function. The TRC105 incorporates a set of low-power states to reduce cur-

rent consumption and extend battery life. The small size and low power con-

sumption of the TRC105 make it ideal for a wide variety of short range radio

applications. The TRC105 complies with Directive 2002/95/EC (RoHS). Pb
