TX2A/RX2G
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.

UHF FM Data Transmitter and Receiver Modules
Features
Designed for compliance with EN 300
Figure 1: RX2G-433-15 & TX2A-433-64
220-3 (radio) and EN 301 489-3 (EMC) standards
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.
