Abstract

The embodiment of the invention provides a mixed dielectric waveguide filter. The mixed dielectric waveguide filter comprises a first three-mode resonator (1), a second three-mode resonator (3) and a single-mode resonator (2), wherein the face, making contact with the single-mode resonator (2), of the first three-mode resonator (1), and he face, making contact with the single-mode resonator (2), of the second three-mode resonator (3) are respectively provided with coupling windows (18 and 38), and dielectric of all the resonators is exposed, and used for coupling between the first three-mode resonator (1) and the single-mode resonator (2) as well as between the second three-mode resonator (3) and the single-mode resonator (2). According to the mixed dielectric waveguide filter, interference between the three-mode resonators can be reduced, and the topological structure is flexible, simple and easy to assemble.

Description

technical field [0001] The invention relates to a radio frequency filter, in particular to a hybrid dielectric waveguide filter. Background technique [0002] With the development of the filter industry, miniaturization and light weight have gradually become a trend. The volume and weight of the filter can be greatly reduced by using a multimode filter. As the technology of dielectric materials matures, the mass production of multimode dielectric resonators can be realized. [0003] At present, there are mainly two types of three-mode filters. The first type is a filter composed of two or more three-mode resonators, such as figure 1 Shown in a kind of existing filter, it comprises two three-mode resonators 5, in order to avoid the influence between two three-mode resonators 5, waveguide transmission line is used between two three-mode resonators 5 6 connections, which can attenuate unwanted modes so that only one mode can be transmitted. The main disadvantage of this solu...
