Precision RF Sensor


The Precision RF Sensor produces scalable DC samples from any directional coupler, providing reliable forward and reflected power indications, permitting accurate VSWR calculation. The sensor connects to the directional coupler through a type “N” Connector and an included RF Pad*. Bring the sample into any remote control system, or use with the Plus-X VSWR for protection of antenna sites with Arcturus or ARC Plus. Each transmission line typically requires two RF sensors, one for forward power and one for reflected power. 

Wide frequency response from 50 to 1000 MHz enables accurate measurement of individual transmitter outputs or multi-channel RF signals such as those found in combined antenna systems. The Precision RF Sensor accommodates signals with high or low peak to average ratios, making it suitable for both analog and digital power measurement. 

The unit can be installed on any directional coupler equipped with a Type N connector, without the need for additional mounting hardware.
