UHF FM Data Receiver Module

Frequency:433.92MHz, 434.42MHz and 434.525MHz

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.

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.


  • Designed for compliance with EN 300 220-3 (radio) and EN 301 489-3 (EMC) standards
  • Data rates up to 64 kbps
  • Usable range up to 300 m
  • Versions available on 433.92MHz, 434.42MHz and 434.525MHz
  • Fully screened
