Description
The RF650 radio transceiver module provides a reliable wireless communications for the transfer of data at
Gaussian Frequency Shift Keying (GFSK), Manchester encoded, RF data rates of up to 100 kbps. Their
unique features of narrow band operation and user channel selection combined with excellent interference
rejection make them an ideal choice for next generation applications. The transceivers have the functions of a
complete radio modem and simply require CMOS/TTL data at the transmit input and the corresponding
transceiver(s) output the same data. Preamble and CRC are automatically generated and added to the RF
transmission.
Operating within the 433MHz band the modules operate in user selectable channels. The RF650 can use any
channel in 100kHz steps. The modules both use a crystal controlled design which provides narrow band
performance which is far superior to other wideband ‘SAW’ based designs.
Possible applications include one-to-one and multi-node wireless links in applications including car and
building security, EPOS, inventory tracking, remote industrial process monitoring and computer networking.
Because of their small size and low power requirements, both modules are ideal for use in portable, battery-
powered applications such as hand-held terminals.
