Radiometrix unveils fast-switching, long-range radio transceiver

Radiometrix has launched the new WFX2 radio transceiver module, said to be ideally suited to industrial applications requiring long range and high-reliability.

The WFX2 promises fast switching together with +27dBm (500mW) RF power output and ETSI Category 1 (Class 1) receiver performance.

It is available for operation in the 500mW 458.5-459.5MHz license-free Industrial/ Commercial Telemetry and Telecommand, Medical and Biological Applications band in the UK and Ireland.

The 256-channel module features an a 5ms RX-to-TX switching time, has a receive sensitivity of -118dBm and can achieve a usable range of over 5km over open ground.

According to Radiometrix, the feature rich interface offers analogue RSSI and both logic level and analogue baseband inputs and outputs. A 4-way internal channel select switch is standard.

Measuring 85 x 55 x 13mm) the module requires a regulated +5V DC power supply and is re-programmable via microcontroller UART interface, drawing 35mA in receive and under 400mA in transmit.

Multiple versions of the product are available; the standard 458MHz module offers data rates of up to 5kbps, the WFX2-458-G variant to be used with external 9600 baud GMSK Modem and a dedicated modem version, the WFZ2 has an internal M48 modem. A 12.5kHz narrowband version is also available.

The WFX2 is ideally suited to industrial applications including on-site paging, telecommand tasks, machine control, fast, long range data modems and robotic/ mechatronic control functions.
