Abstract

The invention relates to the filtering field and discloses a low frequency coaxial cavity filter which comprises a single cavity body, a loading capacitor, a screw, a resonance bar and a stop block; the loading capacitor, the screw, the resonance bar and the stop block are located in the single cavity body; the loading capacitor and the resonance bar are connected by the screw; the screw is located at the top end part of the resonance bar; the stop block is located below the loading capacitor. The low frequency coaxial cavity filter has the advantages that the design accuracy is improved, the design time is accelerated, and the development cost is reduced.

Description

technical field [0001] The invention relates to the field of filtering, in particular to a low-frequency coaxial cavity filter and a manufacturing method thereof. Background technique [0002] The filter is one of the important devices in the operation of the microwave communication system, especially the coaxial cavity filter between 200MHz and 500MHz, which is more used in private network communication projects. For low-frequency (200Mhz-500Mhz) coaxial cavity filters, although the existing design technology basically meets the customer's requirements, the existing design methods basically do not consider the cost control and the size of the filter, or After the customer limits the cost and the size of the filter, the existing technology will lead to a corresponding increase in the difficulty of design and production. For low-frequency (200Mhz-500Mhz) coaxial cavity filters, although the existing design technology basically meets the customer's requirements, the existing ...
