Semtech Corporation SX1231

The SX1231 is a highly integrated RF transceiver capable of operation over a wide frequency range, including the 433, 868 and 915 MHz license-free ISM (Industry Scientific and Medical) frequency bands. Its highly integrated architecture allows for a minimum of external components whilst maintaining maximum design flexibility. The SX1231 offers the unique advantage of programmable narrow-band and wide-band communication modes without the need to modify external components.

GENERAL DESCRIPTION

All major RF communication parameters are programmable and most of them can be dynamically set. The SX1231 is optimized for low power consumption while offering high RF output power and channelized operation, suitable for both the European (ETSI EN 300-220-1) and the North American (FCC part 15) regulatory standards. TrueRF™ technology enables a lowcost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations. KEY PRODUCT
