Abstract

The invention relates to a continuous electric-control resonant cavity and a control system thereof. The resonant cavity comprises a cylinder, wherein the cylinder comprises barium strontium titanate,a cylindrical hole is formed in the cylinder along a direction of an axis, a first electrode is attached onto an outer side of the cylinder, a second electrode is attached onto an inner wall of the cylindrical hole, the first electrode is in contact with an external conductor, the second electrode is in contact with a central conductor, a first coupling ring and a second coupling ring are furtherarranged in the resonant cavity, the first coupling ring is used for injecting a microwave signal into the resonant cavity, and the second coupling ring is used for outputting the microwave signal from the resonant cavity. With the resonant cavity provided by the technical scheme of the invention, electric-control adjustment can be performed the resonant frequency of the resonant cavity.

Description

technical field [0001] The present application relates to the field of microwave technology, in particular to a continuous electronically controlled resonant cavity and its control system. Background technique [0002] At present, the microwave resonant cavity detectors and microwave resonant cavity narrowband filters mainly implement frequency modulation by changing the length of the resonant cavity, adding a medium, and selecting higher harmonics. [0003] Among them, when changing the length of the resonant cavity, the frequency can be increased or decreased by increasing or decreasing the size of the resonant cavity, but due to the limitations of the cutoff frequency and usage scenarios, the size of the resonant cavity cannot be increased or decreased infinitely. In addition, the smaller the size, the higher the requirements for the precision of the components and the manufacturing process. Therefore, the increase of the resonant frequency through the adjustment of the s...
