Description
Technical field
The utility model relates to a kind of electric tuning antenna of base station phase shifter, particularly a kind of phase shifter with power dividing function.
Background technology
Along with the development of Mobile Communications Market and perfect, people have higher requirement to communication quality, because the signal cover of each cellular cell and telephone traffic are not quite similar, also to suppress the signal disturbing to neighbor cell simultaneously, now need the coverage adjusting and optimize this community, need in actual applications to carry out in good time reasonably adjustment to the tilt angled down of antenna for base station vertical plane wave beam, the application of the continuously adjustable electrical tilt antenna of angle of declination, to different districts, under different time, the adjustment of antenna for base station vertical plane wave beam provides great convenience.And phase shifter is as the core component of electrical tilt antenna, the quality of its structural behaviour will directly affect the performance quality of electrical tilt antenna.The phase shifter of design in the past can only carry out phase change, and outside phase shifter, bamboo product power splitter, forms feeding network together with phase shifter.The more complicated that such feeding network just becomes, all brings very large inconvenience to production and assembling, and the linearity of phase shifter amplitude and phase place change in phase place change procedure is not very well, is so just difficult to the electrical tilt antenna designing high-performance high target.
Summary of the invention
The utility model devises that a kind of structure is simple, volume is little, amplitude-phase consistency is good and comprises the integrated phase shifter of power distributing network.
In order to realize foregoing invention object, the utility model adopts following technical scheme:
A kind of phase shifter with power dividing function, comprise metallic cavity, fixing circuit board, walking circuit plate, phase shifter slide plate, pressure bullet pad, described metallic cavity is used for fixing described fixing circuit board, and the bottom centre position of described wire chamber is provided with gathering sill; Described walking circuit plate is provided with a U-shaped microstrip circuit, and the centre of described walking circuit plate is provided with two through holes; Described phase shifter slide plate core is provided with two guide pads, matches with gathering sill in the through hole of two on walking circuit plate and metallic cavity.
Preferably, around the shell body of described metallic cavity, there is location hole, for the location of fixing circuit board and fixing.
Preferably, described fixing circuit board and described walking circuit plate are printed circuit board (PCB).
Preferably, the circuit design on described fixing circuit board is power splitter cascade.
Preferably, pressure bullet pad is provided with between described walking circuit plate and described phase shifter slide plate.
Preferably, the cross section of described pressure bullet pad becomes X-type.
The beneficial effects of the utility model are, drive walking circuit plate to move, thus change the length of transmission line, antenna element phase place is changed by phase shifter slide plate.Phase shifter and power splitter merge and design in one piece of PCB substrate, and power splitter is cascaded up by phase shifter, makes antenna element phase place can become multiple relationship change.The slide plate of phase shifter does not directly contact with standing part, and centre adds deielectric-coating, and signal between the two, by coupled transfer, avoids Metal Phase mutual friction and produces spark while inhibit intermodulation.Add elastic fluid between slide plate and slide plate fixed head, can keep slide plate in moving process all the time with substrates into intimate contact, ensure that the stability of Signal transmissions.

Embodiment
Be described in further detail of the present utility model below with reference to accompanying drawing.
As shown in Figure 1, the utility model, comprises metallic cavity 1, fixing circuit board 2, walking circuit plate 3, phase shifter slide plate 5, pressure bullet pad 4.
As shown in Figure 2, metallic cavity 1 is for the fixing circuit board 2 of fixed phase shifter, and metallic cavity 1 adopts aluminium alloy to draw, and the bottom centre position of metallic cavity 1 is provided with gathering sill 6, moves in slip for phase shifter slide plate 5 along the direction of gathering sill 6; There is location hole 8 around the shell body of metallic cavity 1, position for fixing circuit board 2 and fix.Metallic cavity 1 is also provided with the cover plate of aluminium matter, after cover plate and metallic cavity 1 being fixed with screw, coordinates with substrates into intimate to compress phase shifter slide plate.
As shown in Figure 3, the fixing circuit board 2 of phase shifter, is made with PCB, and phase shifter circuit size is diminished, and consistency is better.The circuit design of fixing circuit board 2 is power splitter cascade, and power splitter has a main power splitter and four from power splitter, and the input of main power splitter is the total input port of signal, and two output branch roads are connected respectively to the top and the bottom feeding network of antenna.Connect the signal of grade circuit from power splitter input, two output branch roads, a branch road is directly connected to antenna element unit by coaxial line, and another branch road is then input to subordinate's circuit.Circuit surface does press mold process, surface is with the medium of 0.3mm, so the circuit on phase shifter slide plate 5 can not directly contact with the circuit on phase shifter fixing circuit board 2, signal passes through coupled transfer, inhibit intermodulation, avoid Metal Phase mutual friction in phase shifter slide plate moving process and produce spark.
As shown in Figure 4, the walking circuit plate 3 of phase shifter, be made with PCB, walking circuit plate 3 is provided with a U-shaped microstrip circuit, phase shifter slide plate 5 drives walking circuit plate 3 to move, thus realize U-shaped microstrip circuit and move, and change the microstrip line length being connected to a period of time unit, thus the phase place of a period of time unit is changed.The centre of walking circuit plate 3 is provided with two through holes.
As shown in Figure 5, phase shifter slide plate 5, forms with hard POM material injection, makes it indeformable in moving process.Phase shifter slide plate 5 core has two guide pads, matches with gathering sill 6 in the through hole of two on walking circuit plate 3 and metallic cavity.Realize phase shifter slide plate 5 and walking circuit plate 3 does not depart from sliding process.By mobile phase shifter slide plate 5, microstrip line length can be elongated, another side microstrip line length then can shorten, to reach the object of phase change.By the mode of cascade, network is linked up, phase place can be made to become multiple relationship change, increase the amount of phase shift of phase shifter.
As shown in Figure 6, pressure bullet pad 4, elastic fluid between walking circuit plate 3 and phase shifter slide plate 5, the cross section of pressure bullet pad 4 becomes X-type, walking circuit plate 3 compresses phase shifter slide plate 5 by pressure bullet pad 4, make phase shifter slide plate 5 in moving process all the time with fixing circuit board 2 close contact, ensure the stability of signal.
