Abstract

A circuit for monitoring the accuracy of the phase shift produced in an r.f. power distribution network in which the phase shift network includes diodes, means for sensing the conductive state of the terminating diodes, and structure for comparing the state of the diodes against a desired condition to provide a warning indication in the event the diodes are not in the proper condition to provide the desired phase shift.
