UHF receiver module

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

When used in conjunction with the company’s matching TX3B-869-64 transmitter, it can facilitate the simple implementation of wireless infrastructure capable of supporting speeds of 64 Kbps and transmission ranges up to 75 m in buildings or 300 m over open ground.

The device has a receive sensitivity of -109 dBm sensitivity at 1 ppm BER for 15 Kbps operation and incorporates a wide range RSSI (received signal strength indicator) which measures the strength of an incoming signal over a range of about 50 dB.

This allows link margins to be quantified, so that judgments on distances that can be supported are easier to make.

Available for operation in the 868.3, 869.5 and 869.85 MHz frequency bands, the module complies with both EN 301 489 and EN 300 220. It is suitable for one-to-one and multi-node wireless link topologies and can be employed in a wide variety of applications, including motor vehicle/building security, environmental monitoring, inventory tracking, remote industrial process control and computer networking.

Current consumption is typically 15 mA and the module is optimised for use in portable, battery-powered wireless design such as handheld terminals.
