Radiometrix announces the availability of its multi-channel 25kHz narrowband transceiver solution with a 500mW (+27dBm) RF output and a receiver sensitivity of -118dBm (for 12dB SINAD), boasting a range of up to 5km. The BHX2's standard operating frequency is the 458.5-459.1MHz UK band, however factory-tuned custom variants covering any 5MHz switching band between 420-480MHz can be supplied.

BHX2

With a supply voltage range of 5.5-15V, the BHX2 draws a current of 350mA for transmitting, and 30mA for receiving. It is particularly suited to low power applications, and offers a means of circumventing the operating range inadequacies of existing multi-channel narrowband devices.

Fitting into a 85x39x13mm package, it offers a total of 128 channels (channel spacing 25kHz), configurable via the RS232 interface. An automatic noise squelching function is activated when there is not any RF signal at detectable levels or if the non-coherent noise is high enough to block out weak signals.

The module delivers data rates of 5kbps. It conforms to both EN 300 220-3 and EN 301 489-3 standards. It incorporates a 1200baud half-duplex modem, which is compatible with that implemented in other Radiometrix devices, allowing easier upgrade.

Target applications for this transceiver include industrial handheld terminals, heavy vehicle/machine remote controls, industrial & commercial telemetry/telecommand systems, high-end security systems, long range data buoy, and vehicle data up/download.
