In one embodiment, a kind of filter, including Medium Wave Guide resonator described in any of the above-described embodiment.

Above-mentioned filter, technical effect are brought by above-mentioned Medium Wave Guide resonator, beneficial effect and above-mentioned Jie The beneficial effect of matter waveguide resonator is identical, without repeating.

Specifically, filter includes multiple Medium Wave Guide resonators, wherein one or two Medium Wave Guide resonator is Using Medium Wave Guide resonator described in any of the above-described embodiment, remaining Medium Wave Guide resonator is different from above-described embodiment institute The Medium Wave Guide resonator stated, using the Medium Wave Guide resonator of script design.In this way, when the port to filter couples When amount is adjusted, by using the port coupling amount adjustment method of Medium Wave Guide resonator described in above-described embodiment to Jie The port coupling amount of matter waveguide resonator is adjusted, can the port coupling amount to filter be adjusted.It may be implemented to hold Mouth close coupling, provides condition to widen the bandwidth of Medium Wave Guide resonator, can be widely applied to the medium wave of broader bandwidth It leads in resonator；Further, since the second coating 22 is located at the side 14 of medium block 10, and the second coating 22 is same for connecting The Signal connector of shaft coupling 40 or pcb board, the design method design when limited by outer dimension it is smaller, in Medium Wave Guide resonator Just there are more preferably design scheme selections when design；In addition, product machining, molding and metallization are simpler, work can be saved When；It, can also be by removing the first metal layer 20 or the second gold medal after being fitted together with the Signal connector of coaxial cable or pcb board The mode for belonging to layer 30 adjusts the coupling amount of port, and production debugging is more efficient, saves debugging cost；Secondly, above-mentioned medium wave It is good to lead resonator consistency, coupling amount is small because changing caused by mismachining tolerance, is suitble to volume production.

Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, all should be considered as described in this specification.

The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
