Abstract

The invention provides an X-and-Ku-waveband power-adjustable microwave source. The device work mode can be changed through regulating the length of an inner conductor, and the X-and-Ku-waveband crossing conversion of the work frequency can be realized.

Description

technical field [0001] The invention relates to the technical field of microwave source devices, in particular to an adjustable high-power microwave source in X and Ku bands. Background technique [0002] High-power microwaves usually refer to electromagnetic waves with a microwave pulse peak power greater than 100MW and a frequency between 1GHz and 300GHz. Since the first high-power microwave source appeared in the early 1970s, high-power microwave source technology has developed rapidly due to the wide range of application requirements in civil and military fields. [0003] Frequency tunability is one of the important development directions of high-power microwave sources, and has important application value in the fields of industry and national defense. The frequency tuning methods of high-power microwave sources mainly include electrical tuning and mechanical tuning. Electrical tuning refers to the realization of operating frequency tuning by changing the applied volt...
