Example Embodiment

[0028] In general, the present invention provides a substrate integrated waveguide filter with an adjustable center frequency. According to the method of electrical adjustment of the resonant frequency of the waveguide, a conductive column is loaded in the filter cavity, and the switch of the conductive column is realized by a conductive film bridge to realize the disturbance of the resonant frequency of the resonant cavity, thereby realizing the substrate integrated waveguide filter The adjustment of the center frequency of the filter greatly increases the application range and calibrability of the filter.

[0029] In terms of manufacturing methods, the present invention uses MEMS technology to manufacture conductive film bridges, that is, the present invention uses MEMS technology and wafer-level manufacturing methods to adjust the center frequency of the substrate integrated waveguide filter by using conductive film bridge switches. Therefore, the present invention integrates ...

Abstract

The invention provides a central frequency adjustable substrate integrated waveguide filter and a manufacturing method thereof. According to an electric adjustment method of the waveguide resonant frequency, tuning conductive poles loaded in a filter resonant cavity, The resonant frequency of the resonant cavity is disturbed, a switch composed of a conductive film bridge is formed on the top metal layer to gate the tuning conductive poles, and the central frequency of the substrate integrated waveguide filter is adjusted. The application range and adjustability of the filter are improved greatly.

Description

technical field [0001] The invention belongs to the technical field of filters, in particular to a substrate integrated waveguide filter with adjustable center frequency and a manufacturing method thereof. Background technique [0002] For high-frequency communication system applications, such as: the high-frequency window of 5G communication, due to the frequency above 27GHz, the traditional microstrip filter has a relatively large in-band insertion loss, and the substrate integrated waveguide (SIW) realizes high-frequency filters due to radiation The loss is very small, so its in-band insertion loss can be controlled in a small range, which is very suitable for application in miniaturized base stations. [0003] The filter is a key component in the radio frequency system. Due to the increase of the operating frequency, the traditional microstrip filter is difficult to meet the requirements of the current radio frequency system due to the increase in loss. Therefore, the su...
