RFMi TRC103 Multi-Channel Low Power UHF RF Transceiver
RFMi TRC103 Multi-Channel Low Power UHF RF Transceiver is a single-chip transceiver designed for low-cost, high volume, two-way short-range wireless applications in the 863MHz to 870MHz, 902MHz to 928MHz, and 950MHz to 960MHz frequency bands. All critical-RF and baseband functions are integrated into the TRC103, minimizing the external component count and simplifying and speeding design-ins. A microcontroller, RF SAW filter, 12.8MHz crystal, and a few passive components create a complete, robust radio function. The TRC103 incorporates a set of low-power states to reduce the overall current consumption and extend battery life. Small size and low power consumption make the RFMi TRC103 Multi-Channel Low Power UHF RF Transceiver ideal for a wide variety of short-range radio applications.Features
