Radiometrix releases UHF radio data receiver

The Radiometrix RX3G is a PLL synthesiser-based miniature PCB-mounted UHF radio data receiver device.

When used in conjunction with the manufacturer's matching TX3B-869-64 transmitters, the receiver can facilitate the implementation of wireless infrastructure that is capable of supporting speeds of 64kbits/s and transmission ranges up to 75m in buildings or 300m over open ground.

The device has a receive sensitivity of -102dBm at 1ppm BER for 64kbits/s operation and -108dBm sensitivity at 1ppm BER for 15kbits/s operation.

It incorporates a wide range RSSI (Received Signal Strength Indicator) that measures the strength of an incoming signal over a range of approximately 50dB.

This allows assessment of the link quality and available margin with which the network can operate, so that a judgment can be made on what distances can be supported.

The device requires a regulated 5V supply with ripple content of less than 100mV peak-to-peak.

Available for operation in the 868.3, 869.5 and 869.85MHz European frequency bands, the product complies with both the EN 301 489-3 EMC (thanks to internal filtering) and EN 300 220-3 radio standards.

It is suitable for one-to-one and multi-node wireless link topologies, and can be employed in a variety of applications, including automobile/building security, environmental monitoring, inventory tracking, remote industrial process control and computer networking.

With its dimensions of 47mm x 16.8mm x 2.5mm and low power requirements (current consumption typically 10mA), the RX3G is optimised for use in portable, battery-powered wireless design such as hand-held terminals.
