Problems solved by technology

[0005] With the development of microwave vacuum electronic devices towards high frequency and miniaturization, the size of bellows is required to be smaller and smaller. However, the development of small-sized bellows is expensive and difficult, and it is difficult to develop springs that meet the requirements.

Abstract

The invention provides an external tuning device for a strip-shaped injection klystron. The strip-shaped klystron external tuning device includes: accommodating cavity, tuning assembly, trapezoidal lever frame and control assembly, which adopts inductive tuning method, and the tuning piston is inserted into the strip-shaped klystron body to form a part of the resonance cavity. Cavity wall; the movement of the tuning piston is controlled by the lever principle, which changes the volume and distributed inductance of the resonant cavity, thereby changing the resonant frequency of the resonant cavity. The invention does not use a bellows, but uses a deformable sealing diaphragm to realize the tuning of the resonant cavity, thereby reducing the cost and simplifying the structure.

Description

technical field [0001] The invention relates to the technical field of microwave vacuum electronic devices, in particular to an external tuning device for a strip-shaped injection klystron. Background technique [0002] In the klystron, the structure and size of the resonant cavity determine its resonant frequency and quality factor, which in turn determines the working characteristics of the klystron. During the tube-making process of the klystron, the size of the resonant cavity deviates from the design value, which leads to the change of the frequency characteristics of the resonant cavity. The klystron resonant cavity tuning technology makes up for the dimensional error caused by the tube making process to a certain extent. [0003] The tuning technology of the resonant cavity is divided into three types: capacitance tuning, inductance tuning and compound tuning. Inductance tuning is to change the volume of the resonant cavity and the distributed inductance of the reso...
