UHF FM Data Receiver


Frequency:433.92MHz, 434.42MHz and 434.525MHz

The TX2C and RX2B 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.

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 TX2C and RX2B 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
