Product Overview

TRC103 is a single chip, multi-channel, low power UHF transceiver. It is designed for low cost, high volume, two-way short range wireless applications in the 863-870, 902-928 and 950-960 MHz frequency bands. The TRC103 is FCC & ETSI certifiable. All critical RF and base-band functions are integrated in the TRC103, minimizing external component count and simplifying and speeding design-ins. A microcontroller, RF SAW filter, 12.8 MHz crystal and a few passive components are all that is needed to create a complete, robust radio function.
