SX1231 RF Transceiver

Semtech's SX1231 optimized for low power consumption while offering high RF output power

Image of Semtech's SX1231 RF Transceiver Semtech's SX1231 is a highly integrated RF transceiver capable of operation over a wide frequency range, including the 433 MHz, 868 MHz, 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. All major RF communication parameters are programmable, and most of them can be dynamically set. The SX1231 offers the unique advantage of programmable narrowband and wideband communication modes without the need to modify external components.

The SX1231 is optimized for low power consumption while offering high RF output power and channelized operation suitable for both European (ETSI EN 300-220-1) and North American (FCC part 15) regulatory standards. TrueRF™ technology enables a low cost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations.
