Radiometrix CXT/CXR module family

Thursday, 17 June, 2010 | Supplied by: RF Modules Australia

Radiometrix has introduced the CXT/CXR module family, a transmitter/receiver pair that provides a remote control switch function for long-range operation where existing wideband cannot offer adequate range or where band congestion requires multiple channel operation.

Supporting data rates of up to 5 Kbps, the modules are built on the radio hardware of the company’s LM series. Like this series, they provide 32 frequency channel operation (12.5 or 25 kHz channels) in the 150.825 to 152.450 MHz frequency band (plus other custom VHF bands are available).

The CXR receiver has a better than -118 dBm usable calling sensitivity, while drawing 20 mA from a 3.1 to 15 V rail. The matching CXT transmitter can be offered in 10 mW (35 mA from 3.1 to 15 V) or 100 mW (95 mA from 4.1 to 15 V) versions.

The integrated control coder/decoder uses a highly noise-tolerant biphase coded data stream, including preamble/framing sequences, CRC error detection to minimise false activations and a 16-bit user programmable address.

All operating parameters (channel, address, frequency table set-up) can be programmed by the user giving an operating range of up to 1 km.
