SX1231IMLTRT

SX1231IMLTRT is a low power integrated UHF transceiver capable of operation over a wide frequency range, including the 433, 868 and 915MHz license-free ISM 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. It offers the unique advantage of programmable narrow-band and wide-band communication modes without the need to modify external components. It is optimized for low power consumption while offering high RF output power and channelized operation. TrueRF™ technology enables a low-cost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations. Application includes automated meter reading, wireless sensor networks, home and building automation, wireless alarm and security systems, industrial monitoring and control, wireless M-BUS.
