The RFM65W-868 is a low-cost 868MHz ISM-band receiver module. All major RF communication parameters are programmable and most of them can be dynamically set. The RFM65W offers the advantage of programmable narrow-band and wide-band communication modes. The RFM65W is optimized for low power consumption while offering high sensitivity and channelized operation. In order to better use RFM65W modules, this specification also involves a large number of the parameters and functions of its core RF65 chip, including those IC pins which are not leaded out. All of these can help customers gain a better understanding of the performance of RFM65W modules. RF Carrier Frequency range: 862 to 890MHz. Modulation: FSK, GFSK, MSK, GMSK or OOK.
