UHF FM Data Transmitter Module

Frequency: 433.92MHz, 434.42MHz and 869.85MHz

The TX2S module is a miniature PCB mounting UHF radio transmitter which enable the simple implementation of a data link at up to 40 kbps at distances up to 75 metres in-building and 300 metres open ground.


  • Complies with EN 300 220-3 and EN 301 489-3
  • Data rates up to 40 kbps
  • Usable range up to 300 m
  • Versions available on 433.92MHz, 434.42MHz and 869.85 (TX3S)
  • Small size: 20x10x2mm (without can), 20x10x2.6mm(with can)



Available for operation at 433.92MHz, 434.42MHz and 869.85MHz in Europe including the UK, both modules combine full internal filtering to ensure EMC compliance by minimising spurious radiations and susceptibilities. The TX2S/TX3S module 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 it’s small size and low power requirements, it is ideal for use in portable, battery-powered wireless devices such as remote control key fob.
