Problems solved by technology

Or through mechanical processing and drilling on the side of the dry-pressed ceramics, but due to the accumulation of errors such as positioning and clamping and processing accuracy during product processing, the production yield will be relatively low, the product consistency will be slightly worse, and the overall cost will increase.
[0006] In the actual product debugging, the above two solutions cannot effectively independently adjust the strength of the port coupling
When the port coupling consistency between products is poor, the debugging yield will be significantly reduced

Abstract

The invention relates to a port coupling structure and a filter. The port coupling structure comprises a groove and a through hole which are located on a medium body and intersect with each other, wherein the groove is located on a first surface of the medium body and extends from the side wall of the medium body to be connected with a frequency tuning blind hole located on the first surface, and the through hole extends from the bottom of the groove to a second surface of the medium body opposite to the first surface. Compared with the prior art, the product reliability is high, the production difficulty is reduced, the product consistency is good, and the port coupling structure is suitable for batch production. In addition, the strength of the port coupling structure has better adjustability, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a communication device, in particular to filter port coupling technology. Background technique [0002] With the construction of 5G communication system, its equipment has higher and higher requirements for integration, and the miniaturization and weight reduction of microwave filters will be the application trend in the future. The dielectric waveguide filter can greatly reduce the size of the product, and has the advantages of high Q value and small temperature drift. It is a good miniaturization solution. [0003] The signal transmission between the signal source (input and output ports) and the filter is realized through the port coupling structure. The strength of this coupling is directly related to the bandwidth of the filter, that is, the wider the filter passband, the stronger the port coupling required. There are mainly two kinds of port coupling schemes of existing dielectric filters. The first option is as Figur...
