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.

Features

Figure 1: TX2A-433-64 & RX2A-433-64

! 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.
