Radiometrix Ltd, TX3A & RX3A Data Sheet

page 1

Features:

Frequencies available as standard: 869.85MHz, 914.5MHz

CE certified by independent Notified Body

Verified to comply with Radio standard EN 300 220-3 by accredited Test Laboratory

Verified to comply with EMC standard EN 301 489-3 by accredited Test Laboratory

North American version conforms to FCC part 15.249

Data rates up to 64kbps

Fully screened

Available for operation in the 868-870MHz band in Europe and the 902–928MHz band in

North America, both modules combine full screening with internal filtering to ensure EMC

compliance by minimising spurious radiation and susceptibility. The TX3A & 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.
