Problems solved by technology

[0004] In prior art, for example figure 1 It is an existing adjustable inductive coupling method. In order to ensure its adjustability, a tuning screw (cylindrical metal coupling) is added. It is necessary to ensure a sufficient distance between the screws to facilitate debugging. For miniaturized filters, it means The distance between the two cavities cannot be close enough, and the coupling coefficient is difficult to improve

Embodiment 1

[0029]Such asFigure 1 ~ 4As shown, those skilled in the art can carry out the modulated sensing coupling structure of a cavity filter as a cavity filter, and there are two resonant cavities and a cylindrical metal, and a rectangle is provided between the two resonant cavities. Cylindrical 333; the rectangular column 333 is coupled to the cylindrical metal, by changing the long-width height of the rectangular cylinder, can sufficiently adjust the coupling strength from the design, which can meet the narrowband demand and achieve broadband strong coupling. By cooperating with a cylindrical metal coupling method (tuning screw), it is satisfied with the adjustability of the production; and the rectangular column 333 is provided between the two resonant cavity bottoms, and the tuning screw 111 is provided; the length of the rectangular column is changed. L, wide, high, and tuning screw length B, square post coupling mating cylindrical coupling; a rectangular cylinder is increased between...

Description

Technical field[0001]The present invention relates to a cavity filter technology, and more particularly to an adjustable sensitive coupling structure of a cavity filter.Background technique[0002]Common coupling structures of cavity filters can be divided into space-coupling, direct coupling, plus ridge coupling, magnetic ring coupling, diaphragm coupling, and probe coupling, which are adjusted to capacitive coupling, and the rest is sensible coupling.[0003]Spatial coupling achieves adjustment of coupling strength by changing the distance between the two harmonic cavities, widely applied to a straight-row-row-like comb or an integer filter design, and its coupling strength can not meet the needs under specific structural dimensional conditions. Direct coupling can provide very strong coupling capabilities, but it is inconvenient for assembly, poor design and adjustability of physical processing. Strong joint coupling capacity, adjustable design, but there is an inconvenient processin...
