Title:
TOWER AMPLIFIER, SIGNAL TRANSMITTING AND RECEIVING DEVICE, CAVITY FILTER AND DIRECTIONAL COUPLED STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2016/101175
Kind Code:
A1
Abstract:
Provided in the present invention are a directional coupled structure of a cavity filter, the directional coupled structure of the cavity filter comprising a coupling piece and a coupling main rod mutually coupled to each other, and a fixed connection block is disposed between the coupling piece and the coupling main rod, the fixed connection block comprising a connection end of the coupling piece and a connection end of the coupling main rod, and the connection end of the coupling piece fixes the coupling piece, and the connection end of the coupling main rod fixes the coupling main rod. Compared to the prior art, the cavity filter and the directional coupling structure thereof provided in the present invention adds a connection fixed block between the coupling piece and the coupling main rod of the directional coupled structure, so as to enable the directional coupled structure of the cavity filter to determine distance and angel between the coupling piece and the coupling main rod via a simple assembly, ensuring consistency of a extend of product coupling of the directional coupled structure of the cavity filter.
