Available for operation in the 868-870MHz band in Europe, it combine full screening with internal

filtering to ensure EMC compliance by minimising spurious radiation and susceptibility. The TX3B and

matching RX3A will suit one-to-one and multi-node wireless links in such applications as car and

building security, EPOS and inventory tracking, remote industrial process monitoring and data

networks. 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.
