Abstract

The invention provides a microwave cavity stability optimization method independent of a circuit and a miniaturization microwave assembly obtained based on the same. The microwave cavity stability optimization method is independent of the structural form and layout of the internal circuit of the microwave cavity; and the stability of the microwave cavity is improved by optimizing the resonance mode of the cavity. In addition, the miniaturization microwave assembly obtained based on the microwave cavity stability optimization method comprises a box body and a cover plate; and a boss is arranged below the cover plate. The length, width, and height of the cavity of the box body are a, b, and c and the length, width, and height of the boss are at, bt, and ct, wherein the at / a is larger than 0 and is smaller than 1, the bt / b is larger than 0 and is smaller than 1, the ct / c is larger than 0 and is smaller than 1. The microwave cavity stability optimization method and the miniaturization microwave assembly have the following beneficial effects: on the basis of the designed cover plate structural form, the Q value of the cavity is reduced and the resonant frequency of the cavity is beyond the working band; the cavity mode optimization is realized by uing the cavity space fully; and the assembly stability is improved.

Description

technical field

[0001] The invention belongs to the field of radio-frequency microwave technology, and in particular relates to a method for optimizing the stability of a microwave cavity independent of a circuit and a miniaturized microwave component obtained based on the method. Background technique

[0002] Phased array radar is widely used because of its advantages of phase scanning, flexible beam pointing, high data rate, simultaneous formation of multiple independent beams, and tasks such as search, tracking, guidance, identification, and passive detection. With the continuous development of science and technology and the diversified needs of modern warfare, the requirements for phased array radar indicators are becoming more and more stringent. Microwave components are the core components of active phased array radar, and their volume, weight, stability and other indicators directly affect the corresponding overall indicators of the radar. Miniaturized and high-stabil...
