UHF FM Data Transmitter and Receiver Modules

The TX2A and RX2G data radio modules

are PLL synthesiser based miniature

PCB mounting UHF radio transmitter

and receiver pair which enable the

simple implementation of a wireless

data link at up to 64 kbps at distances

up to 75 metres in-building and 300

metres open ground.

Features

 Designed for compliance with EN 300

220-3 (radio) and EN 301 489-3 (EMC) standards

Figure 1: RX2G-433-15 & TX2A-433-64

 Data rates up to 128kbps

 Usable range up to 300m

 Versions available on 433.92MHz, 434.42MHz and 434.525MHz

 Fully screened

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.
