Abstract

A cavity resonator based on a deformable high-temperature superconducting material of the present invention includes a resonator cavity, and the deformable high-temperature superconducting material is attached to the surface of the circuit structure of the resonator cavity in a completely covered manner and electrically connected to each other. connected to form a superconducting cavity. The electrical connection between the deformable high-temperature superconducting materials is realized in the form of conductive adhesive bonding and / or welding. Beneficial effects: the deformable high-temperature superconducting material is introduced into the existing cavity filter / resonator design, and the cavity superconducting filter design is realized. Utilizing the characteristics of deformable high-temperature superconducting strips that are easy to process and not easy to break, a tuning structure that can adjust the internal size of the resonator is designed, which provides a new tuning method for the cavity superconducting resonator / filter and reduces the resonator. The difficulty of design also reduces the accuracy requirements for resonator processing. When designing the circuit, the difference between the frequency of the target circuit and the target circuit is designed, and at the same time, the problem of product stability after tuning is solved.
