Wireless link delivers +27dBm power output over a 5 km range

July 30, 2012 // By Julien Happich
The WFX2 radio transceiver module launched by Radiometrix is well suited to industrial applications requiring long range and high-reliability, combining fast switching together with +27dBm (500mW) RF power output and ETSI Category 1 (Class 1) receiver performance.

The WFX2 is available for operation in the 500 mW, 458.5-459.5MHz license-free industrial/commercial telemetry and telecommand, medical and biological applications band in the UK and Ireland.

This 256-channel module features an RX-to-TX switching time of 5 ms, has a receive sensitivity of -118 dBm and can achieve a usable range of over 5 km over open ground. 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. The 85- x 55- x 13-mm unit requires a regulated +5V DC power supply and is re-programmable via microcontroller UART interface, drawing 35 mA in receive and under 40 0mA in transmit. Multiple versions of the product are available; the standard 458 MHz module offers data rates of up to 5 kbps, 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 12.5 kHz narrowband version is also available.
