Description
Technical field
The utility model relates to one and has positive and negative convertible cross-linked waveguide duplexer, belongs 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 purpose of this utility model is the deficiency overcoming prior art existence, provides one to have positive and negative convertible cross-linked waveguide duplexer.
The purpose of this utility model 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 solutions of the utility model 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
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Fig. 1: organigram of the present utility model.
Embodiment
As shown in Figure 1, there is positive and negative convertible cross-linked waveguide duplexer, the cover plate 1 comprising cavity 2 and be located thereon, cavity 2 is rectangular structure, the duplexer that waveguide transmission path filter and receiving path filter form is provided with in cavity 2, each path is made up of some waveguide resonant cavities and coupling window, be provided with the consistent H face slit window coupled structure 3 of main coupling between non-adjacent chamber, the cover plate corresponding with coupled structure position is provided with adjusting screw(rod) 4, and adjusting screw(rod) 4 stretches in coupled structure 3.
Cover plate 1 is welded on to reach better sealing on cavity 2, and prevent signals leakiness, not only volume is little, with low cost for this positive and negative convertible cross-linked duplexer, and is easy to realize.During assembling, first cavity is fixed on point gum machine and carries out a glue, then cover cover plate and stamp screw, then entirety is welded by high temperature furnace, then load onto adjusting screw(rod) 4.
Cross-couplings between the non-adjacent chamber realizing quasi-elliptic function transmission response adopts with the consistent H face slit window coupled structure 3 of main coupling, cover plate is provided with very little adjusting screw(rod) 4, the insert depth utilizing adjusting screw(rod) 4 different in coupling window is dexterously to electromagnetic interference, successfully convert cross-linked positive negative characteristic, make it 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 same channel filter design can be used for send can be used for again receive, it can also be made to work in different subbands by tuning adjusting screw(rod) 4 becomes possibility.Structure is simple, is easy to manufacture, and stable performance, cost is low, is applicable to large-scale production.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
