Coaxial-to-microstrip connector suitable for cavity filter and assembling method

Abstract

The invention discloses a coaxial-to-microstrip connector suitable for a cavity filter and an assembling method, and relates to the connector technical filed. The coaxial-to-microstrip connector comprises a substrate capable of being simultaneously connected with the cavity filter and a microwave circuit, a microstrip cavity is formed at one side of the substrate, and an air transition cavity penetrating to the other side of the substrate is formed at one end, far away from an opening, in the microstrip cavity. By using the coaxial-to-microstrip connector, the impedance matching characteristicof the cavity filter at the coaxial-to-microstrip position in a microwave integrated circuit is ensured, the debugging workload of the debugging personnel is greatly reduced, at the same time, the consistency of products is ensured, and the working efficiency is improved.

Description

technical field

[0001] The present application relates to the field of microwave technology, in particular to a coaxial-to-microstrip connector and an assembly method for a cavity filter. Background technique

[0002] Cavity filter is a passive device used in frequency distribution and frequency selection in microwave system in electronic equipment system. It is widely used in frequency source, switching filter bank and other systems due to its advantages of large bandwidth and high isolation. Cavity filter is a two-port device, which also has important functions such as signal isolation and interference suppression. It is widely used in modern microwave and millimeter wave communication, satellite communication, remote sensing and radar technology and other systems. The quality of its performance directly affects the running quality of the whole system.

[0003] The traditional method of using the cavity filter is to design the dual ports of the cavity filter as input and ...
