SX1239 Datasheet | SEMTECH

SCRIPTION The SX1239 is a highly integrated RF receiver 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 ponents whilst maintaining maximum design flexibility. All major RF munication parameters are programmable and most of them can be dynamically set. The SX1239 offers the unique advantage of programmable narrow-band and wide-band munication modes without the need to modify external ponents. The SX1239 is optimized for low power consumption while offering high sensitivity and channelized operation. True RF™ technology enables a lowcost external ponent count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations.
