TX2A/RX2A
UHF FM Data Transmitter and Receiver Modules
The TX2A and RX2A data link
modules are a miniature PCB
mounting UHF radio transmitter
and receiver pair which enable the
simple implementation of a data
link at up to 64 kbps at distances up
to 75 metres in-building and 300
metres open ground.

!
CE certified by independent Notified Body
Verified to comply with harmonised radio standard EN 300 220-3 and EMC standard EN 301 489-
3 by accredited Test Laboratory
Data rates up to 64 kbps
Usable range up to 300 m
Versions available on 433.92MHz and 434.42MHz
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 RX2A 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.
