Available for operation at 433.92MHz or 434.42MHz in the UK and Europe, both modules combine full
screening with extensive internal filtering to ensure EMC compliance by minimising spurious radiations
and susceptibilities. The TX2A and RX2G modules will suit one-to-one and multi-node wireless links in
applications including car and building security, EPOS and 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.

... The TX2A module is type approved to EN 300 220-3 for European use and delivers nominally +10dBm at 11mA. The module measures 3.8 mm. The RX2G module is a single conversion FM superhet receiver capable of handling data rates 64kbps. RX2G needs a regulated 5V supply and draws 10mA when receiving. The RX2G features a fast power-up time for effective duty cycle power saving and a signal strength (RSSI) output with 50dB of range ...
