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 down-
mode.
