Switching of Microwave Radiation Storage and Output Modes in Superconducting Resonance-Cavity Compressors with an Interference Switch.

We propose a commutator for the interference switch of microwave electromagnetic radiation on the basis of a waveguide H-junction made as a cavity with tunable parameters, which is connected to one arm of this junction. The superconducting version of a microwave compressor with such a switch is analyzed. The conditions of effective switch operation in the mode of electromagnetic energy storage and its fast output in the case of controllable manipulation of the Q-factor and resonant frequency of the switching cavity are determined. Estimates of the output parameters of the superconducting compression system are presented for storing- and switching-cavity Q-factors of about 5 ・ 10. The possibility of increasing the radiated power in such a compression system by 40-60 dB for output microwave pulses with durations of about 5-10 ns is demonstrated. Variants of practical implementation of the system are considered. [ABSTRACT FROM AUTHOR]
