Multi-channel VHF narrowband radio transceiver

May 10, 2010 // Julien Happich

Radiometrix discloses a compact multi-channel operation VHF radio module the company plans to exhibit at National Electronics Week held between the 18th and 19th May in Birmingham. The SHX1 narrowband transceiver is powered by a +5V regulated supply and has an output power of 500 mW, allowing it to cover a range of over 5 km. The transceiver is usable in any 3 MHz segment of the 140 MHz to 175 MHz frequency range, making it suitable for use in wireless communication based on the 144 MHz amateur, 151 MHz United States' Multi Use Radio Service (MURS), and European 169 MHz bands.

The standard module can offer data rates of up to 5 kbps, and supports 8 parallel or 255 serial channels. It conforms fully to both the ETSI EN 300 220-3 and EN 301 489-3 electromagnetic compatibility standards.

As the SHX1 has separate N and R registers on each channel for transmit and receive functions, the frequency of each of these channels can be individually programmed in every mode. Other possible applications include industrial/commercial telemetry systems, high-end security alarms, automatic packet reporting systems, vehicle data up/download, and remotely operated vehicle/machinery controls.
