Characterization of microwave integrated circuits using an optical phase-locking and sampling system

Abstract
Using an optical technique, phase-locked microwave signals of up to 15 GHz from voltage-controlled oscillators have been achieved. Combining this technique with a photoconductive switch, a novel microwave waveform sampling system that displays the characteristics of oscillators and amplifiers has been demonstrated. The approach has potential applications for optically phase-locked microwave subsystems and monolithic integrated circuit characterizations.<>
