Abstract : The report contains the experimental and theoretical results obtained in a study to further develop an electronically controllable microwave window used as a single-pole, single-throw switch. Fabrication improvement and structure optimization resulted in advancing, by more than an order of magnitude, the state of the art in high-power broad-band semiconductor microwave switches at S- and X-band frequencies. A discussion is given of the microwave operating characteristics of the window which are basic for optimizing the window design. The recombination mechanisms present in the device are discussed. An account is given of the fabrication procedures used in the practical realization of the devices. The microwave mounts used for both S- and X-band windows are described. The results of the microwave tests carried out in the fabricated windows for determining their switching characteristics are presented. (Author)
