433MHz FM Transmitter


The TX2A is a 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 meters.



  • 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.
