Abstract
The invention relates to a waveguide duplexer with positive and negative convertible cross coupling. The waveguide duplexer with the positive and negative convertible cross coupling comprises a chamber and a cover plate which is arranged on the chamber; a duplexer which is formed by a waveguide transmitting channel filter and a receiving channel filter is arranged inside the chamber; every channel is formed by a plurality of waveguide resonant chambers and coupling windows; an H-surface slit window coupled structure which is consistent with main coupling is formed between non-adjacent chambers; the cover plate position which is corresponding to a coupled structure position is provided with an adjusting screw; the adjusting screw is extended into the coupled structure. According to the waveguide duplexer with the positive and negative convertible cross coupling, cross coupling between the non-adjacent chambers are in the H-surface slit window coupled structure which is consistent to the main coupling, electromagnetic waves of the cross coupling are skillfully interfered by adjusting the embedding depth of the screw in a coupling window to be easily converted between the positive coupling property and the negative coupling property, a positive coupling property and negative coupling property integrated coupled structure is achieved, a conversion requirement for transmission zero response in the high frequency side or low frequency side in actual applications is satisfied, and the same channel filter design can be used for transmitting and receiving.
Description
Technical field
The present invention relates to one and there is positive and negative convertible cross-linked waveguide duplexer, belong to microwave telecommunication devices technical field.
Background technology
Waveguide duplexer is a passive device, transmitting can be separated with the microwave signal accepting frequency range, when needing to realize low loss, during isolation between high transmitting and receiving signal, just need the cross-couplings of the plus or minus added between non-adjacent chamber, to realize the transmission response of quasi-elliptic function.Usual positive and negative cross-couplings needs independent coupled structure to realize respectively, and especially with the more difficult realization of negative coupling, the complex structure of needs, causes volume to increase, and cost increases.
Summary of the invention
The object of the invention is the deficiency overcoming prior art existence, provide one to have positive and negative convertible cross-linked waveguide duplexer.
Object of the present invention is achieved through the following technical solutions:
There is positive and negative convertible cross-linked waveguide duplexer, feature is: the cover plate comprising cavity and be located thereon, the duplexer that waveguide transmission path filter and receiving path filter form is provided with in cavity, each path is made up of some waveguide resonant cavities and coupling window, be provided with the consistent H face slit window coupled structure of main coupling between non-adjacent chamber, the cover plate corresponding with coupled structure position is provided with adjusting screw(rod), and adjusting screw(rod) stretches in coupled structure.
Further, above-mentioned has positive and negative convertible cross-linked waveguide duplexer, and wherein, described cavity is rectangular structure.
Further, above-mentioned has positive and negative convertible cross-linked waveguide duplexer, and wherein, described bridge welding is connected on cavity.
Substantive distinguishing features and the progress of technical solution of the present invention are mainly reflected in:
Cross-couplings between non-adjacent chamber adopts with the consistent H face slit window coupled structure of main coupling, adding very little adjusting screw(rod) in it is placed on cover plate, by the insert depth of adjusting screw(rod) in coupling window, disturb cross-linked electromagnetic wave dexterously, it is made to change easily between positive and negative coupled characteristic, that is achieve the integrated coupled structure of positive negative characteristic, then easily meet in practical application or high frequency side or lower frequency side transmission zero response conversion demand, make the design of same channel filter can be used for transmission can be used for again receiving, it can also be made to work in different subbands by tuning screw and become possibility, its structure is simple, be easy to manufacture, performance is excellent, cost is low, be easy to batch production.
Accompanying drawing explanation
