Overview
RF2926 11 Typical Applications • Wireless Meter Reading • Keyless Entry Systems • 433/868/915MHz ISM Band Systems • Wireless Data Transceiver • Wireless Security Systems • Battery Powered Portable Devices UHF DUAL CONVERSION TRANSCEIVER Product Description The RF2926 is a monolithic integrated circuit intended for use as a low cost FM transceiver.
The device is provided in 48-lead plastic TQFP packaging and is designed to provide a dual conversion, half-duplex transceiver.
The chip is intended for linear (AM, FM) or digital (ASK, FSK, OOK) applications in the North American 915MHz and European 433/868MHz ISM bands.
The integrated VCO has a buffered output to feed the RF signal back to the PLL IC to form the frequency synthesizer.
Separate RX ENABL, TX ENABL, and PLL ENABL lines allow for half duplex operation as well as turning on the VCO to give the synthesizer time to settle and complete power downmode.
