1. Descriptions of RF Transceiver Module RFM69W:

The RFM69W is a highly integrated RF transceiver 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 components whilst maintaining maximum design flexibility. All major RF communication parameters are programmable and most of them  can  be  dynamically set. 

The  RFM69W  offers  the unique advantage of programmable narrow-band and wide- band communication modes without the need to modify external components. The RFM69W 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.
