摘要

. In this talk, our recent investigations of high-power microwave switching based on a low temperature are discussed. Specifically, the proposed switch is composed of an evanescent-mode cavity resonator loaded with a gas discharge tube (GDT) in the gap over the resonator post. Preliminary results demonstrate successful performance up to 10s of W. Insertion loss of such a switch would be the same as the resonator loss, and its isolation depends directly on the level of input power. In comparison with other microwave switching technologies, the proposed plasma-based switch can handle higher power and temperature while introducing less nonlinearity in its off-mode, whic makes it attractive for emerging high-power applications.
