Effect of Detector Mismatch on Passive Hybrid-tee Microwave Discriminator Operation

Abstract

A passive microwave discriminator has been implemented at 9.928 GHz and its frequency response measured in presence of reflection from the unmatched diode detectors used in its implementation. Effect of detector mismatch on the discriminator operation has been estimated experimentally and theoretically.
