Booster board for RF modules

27 February 2002 Telecoms, Datacoms, Wireless, IoT

The RHM092 is a booster board designed specifically for the Radiometrix TX2 and TXM modules.

The Radiometrix module fits onto the back of the booster board; all pins are compatible with the TX2 or TXM, thus allowing direct replacement without taking up much space. The board measures 31 x 17 mm and operates on 5 V d.c. Output power is +20 dBm (TX2) or +17 dBm (TXM), second harmonic is -45 dBc. Current consumption without the heater is 100 mA.

An optional heater can be fitted to the board to extend the negative operating temperature.

The heater when powered consumes 50 mA and should extend the operating range to -25°C. The above specifications are preliminary prototype test results.
