Abstract

Optical-microwave transducers based on FET devices are investigated to determine their dynamic characteristics. It is observed that the result of the well known frequency response method differs from that of a combined test method applying simultaneously a microwave signal and a modulated lightwave for driving the transducer. Based on these investigations a more precise circuit model is established for illuminated FET devices. The new circuit model describes the operation of optical-microwave transducers like mixers, phase detectors, amplifiers, injection locked oscillators, and modulators.<>
