Semtech SX1209

The SX1209 is a highly integrated RF transceiver capable of operation from 290 MHz to 928 MHz, including the 315 and 434 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 SX1209 offers the unique advantage of programmable narrow-band and wide-band communication modes without the need to modify external components. The SX1209 is optimized for low power consumption while offering high RF output power and channelized operation. TrueRFâ„¢ technology enables a low-cost external component count (elimination of the SAW filter) whilst still satisfying ETSI and FCC regulations.
