RF Transceiver
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.
