Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
In order to make utility model technical problem to be solved, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that described specific embodiment is only in order to explain the utility model, and need not limit the utility model.
Fig. 1 is the schematic three dimensional views of an embodiment of the utility model phase shifter, and Fig. 2 is the schematic diagram of interior metal band line, the schematic three dimensional views that Fig. 3 is another embodiment.
As shown in Figure 1, phase shifter of the present invention comprises metallic cavity 11 and upper cover plate 12; Dividing plate 13 is separated into two chambers cavity.Metallic cavity 11, upper cover plate 12 and metal micro-strip line 21,22 and U-shaped metallic conductor adopt die cast, to meet the requirement of production in enormous quantities;
In each chamber 15, be provided with the metal micro-strip line 21 and 22 and a U-shaped metallic conductor 23 of two parallel placements.On U-shaped conductor, connect a plastic tie 25, metal micro-strip line 21 and 22 is with how much, partition 14 centers symmetry, respectively have the square-section groove 41 of one section of hollow, extend to metal micro-strip line one end one end of section slot, and the other end extends to the metal micro-strip line other end and communicates with the external world; In each chamber, be provided with a U-shaped metallic conductor, U-shaped metallic conductor 23 can horizontally slip in the groove of square-section, the length that metallic conductor 23 embeds in guide rail changes, thereby the air microstrip line length forming with metal micro-strip line 21 and 22 changes, and has reached the object of the change of signal transmission phase place.
For fear of the position deviation of metal micro-strip line 21 and 22, can described metal tape line be fixed in chamber 15 by insulated support.
Insulation processing has been carried out on described U-shaped metallic conductor surface, can avoid like this impact on third order intermodulation index, guarantees good intermodulation performance.
As shown in Figure 2, described metal micro-strip line 21 is connected by power feed hole 41 with the inner wire of coaxial cable 30; Metal micro-strip line can coordinate plastic support post to be fixed in chamber 15 by support column 43.
