1. Descriptions of Wireless RF Sub-GHz Transceiver Module RFM64W:

The  RFM64W  is  a  programmable low  cost  low power long range single-chip wireless RF transceiver module operating  in  the  frequency  ranges  from  300MHz  to 510MHz. The RFM64W is optimized for very low power  consumption (3mA in receiver mode). 

It incorporates a baseband modem with data rates up to 150 kb/s. Data handling  features  include  a  sixty-four  byte   FIFO, packet handling, automatic CRC generation  and data whitening. Its highly integrated architecture  allows for minimum external component count whilst  maintaining design flexibility. A

ll major RF  communication parameters are programmable and  most of them may be dynamically set. It complies with  European (ETSI EN 300-220 V2.1.1) and North American  (FCC part15.247 and 15.249) regulatory standards.
