Abstract

The invention provides a dielectric waveguide filter with adjustable port coupling strength. The dielectric waveguide filter comprises at least one resonance unit, at least one port blind hole and atleast one port inner core, wherein the port blind hole is formed in the surface of the dielectric waveguide filter, and the port blind hole is provided with at least one non-electroplating area; and the port inner core is arranged in the port blind hole, and the coupling strength of the port is adjusted by adjusting the area of the non-electroplating area and the length of the port inner core extending into the port blind hole. According to the invention, the port coupling strength of the dielectric waveguide filter can be flexibly adjusted only by processing the port blind hole through a conventional electroplating process; the method has the advantages of being simple in implementation mode and easy to operate; the number of scrapped materials is reduced; and the production cost is reduced.

Description

technical field [0001] The invention relates to dielectric waveguide filter technology in the field of communication technology, in particular to a dielectric waveguide filter with adjustable port coupling strength. Background technique [0002] With the continuous development of modern communication technology, the requirements for filter performance indicators are also getting higher and higher. Due to its small size, high Q value, and low cost, dielectric waveguide filters have been well applied in miniaturized and highly integrated communication systems. The production of the existing dielectric waveguide filter is an irreversible process, and the port coupling of the produced dielectric waveguide filter cannot be adjusted flexibly. Once there is a problem with the port coupling, it will be difficult to achieve the expected index of the dielectric waveguide filter to a large extent. Cause material waste. Therefore, how to realize the adjustable port coupling strength p...
