Abstract

The invention discloses a waveguide filter, which relates to the technical field of wireless communication. The waveguide filter includes a first waveguide flange, a second waveguide flange and a slotted circular waveguide. A rectangular groove is formed on the side wall of the slotted circular waveguide, which facilitates metal plating on the inner surface of the structure of the slotted circularwaveguide during the machining process, and reduces the quality of the waveguide filter. A manufacture method of the waveguide filter is also disclosed. The waveguide filter structure is integrally printed by adopting a non-metallic material through a stereo photolithography 3-D printer and metal plating of the whole inner and outer surface of the waveguide filter is realized, which realizes precise machining without assembling and debugging, effectively improves the manufacturing efficiency.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a waveguide filter and a manufacturing method thereof. Background technique [0002] With the development of wireless communication technology, modern advanced radio communication systems require high-performance and multi-functional microwave and millimeter-wave devices to adapt to complex and changeable electromagnetic environments. In these radio communication systems, especially the RF front-end transceiver systems, traditional microwave and millimeter wave passive waveguide devices, such as waveguide filters, have the advantages of diversified RF functions, low RF insertion loss and large power capacity, and are of great concern to researchers. one of the key points. [0003] Waveguide devices with complex RF functions often have complex three-dimensional physical structures. When manufacturing these devices using traditional machining processes, it is necess...
