Burk Technology PRF-1

The PRF-1 Precision RF Sensor produces scalable DC samples from any directional coupler. The sensor provides reliable forward and reflected power indications permitting accurate VSWR calculation. Bring the sample into any remote control system or use with the Plus-X VSWR. Each transmission line typically requires two RF sensors, one for forward power and one for reflected power.

Wide frequency response from 6 MHz to 1000 MHz enables accurate measurement of individual transmitter outputs or multichannel 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.
