Problems solved by technology
If the amount of coupling cannot meet the requirements, reprocessing and replacement of the coupling structure is required, resulting in low production efficiency and poor processing consistency
[0004] However, due to the unavoidable processing errors in the processing of metal coupling elements or metal sheet materials, some high-demand products often have different actual coupling strengths due to material processing errors during mass production.
In particular, when the processing error of the metal coupling element or metal sheet causes the product to fail to meet the actual required coupling amount or coupling strength, the existing non-contact coupling structure cannot make up for it
This will lead to the failure of product indicators to meet the standards, poor product performance, and poor consistency of parameters for mass-produced products

An adjustable coupling structure and a communication front-end device element are provided. The adjustable coupling structure is provided with a metal coupling sheet which is arranged between two resonant rods without electrical contact. Adjusting screws are added between the metal coupling sheet and the resonant rods, and each adjusting screw is parallel to the adjacent resonant rod. Each adjusting screw is fixed by an adjusting nut, and the height of each adjusting screw relative to the metal coupling sheet and / or the resonant rods is adjusted by the adjusting nut. Because of the arrangement, the adjusting screws can be coupled to the metal coupling sheet and the resonant rods at the same time to realize the adjustment of the cross-coupling strength in the signal channel of the communication front-end device element. In the invention, the adjusting screws are coupled to the metal coupling sheet and the resonant rods at the same time, so that the coupling amount between the metal coupling sheet and the resonant rods can be changed, and the coupling strength between coupling components and the resonant rods can be greatly improved. The adjustable coupling structure and the communication front-end device element of the invention have the advantages of simple structure, strong operability, good batch consistency and low implementation cost.
Description
technical field [0001] The invention relates to microwave communication devices, in particular to an adjustable coupling structure and communication front-end equipment components. Background technique [0002] Components such as duplexers, combiners, and filters are widely used in front-end equipment in the communication field, and their product performance will directly affect the overall communication quality. In the product design process of such communication front-end equipment components, it is often necessary to use non-contact coupling structures such as coupling elements and resonant rods to achieve technical indicators such as capacitive cross-coupling and tap coupling. [0003] However, the existing non-contact coupling structure usually uses a metal sheet with a specific size to directly couple with the resonant rod. In this coupling structure, when the metal coupling element or metal sheet is coupled with the resonant rod, the coupling amount is directly deter...
