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 SX1239 offers the unique advantage of programmable narrow-band and wide-band communication modes without the need to modify external components. The SX1239 is optimized for low power consumption while offering high sensitivity and channelized operation. TrueRF™ technology enables a lowcost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations.
