Abstract
The invention provides a power divider comprising a first connector, a cavity, and a second connector. The cavity comprises an output chamber and an input chamber which are integrally formed and which are vertically connected. The input chamber is equipped with multiple installing holes. A side, far from the input chamber, of the output chamber is provided with an inwardly-recessed stepped standing wave matching structure which comprises three steps. The sum of the heights of the three steps is equal to a quarter of a [lambda] and the sum of the widths of the three steps is equal to a [lambda]. One end, far from the output chamber, of the input chamber is in threaded connection with the first connector. Both ends of the output chamber are in threaded connection with the second connector. Rubber sealing pads are arranged on the junction of the first connector and the cavity and the junction of the second connector and the cavity. The first connector is in a circular shape and the second connector is in a square shape. The power divider may enlarge the frequency coverage.
Description
Technical field
The present invention relates to communication technique field, particularly relate to a kind of power splitter.
Background technology
Power splitter is a kind of comparatively general passive device, and its function is the signal of input is separated equal or two-way not etc. or multiple signals, plays the effect of power division.The impedance bandwidth of existing power splitter is smaller, is all only only limitted to some single frequency ranges, so frequency coverage is narrower, can not meet the requirement of Ultra-wideband Communication Technology to standing wave.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of power splitter, can improve frequency coverage.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of power splitter, comprise the first connector, cavity and the second connector, described cavity comprises integrated output cavity and input cavity, described output cavity is vertically connected with described input cavity, described input cavity is provided with multiple installing hole, away from the side of described input cavity, there is the stairstepping standing wave matching structure concaved at described output cavity, described stairstepping standing wave matching structure comprises three grades of ladders, the height sum of described three grades of ladders is 1/4 λ, the width sum of described three grades of ladders is λ, described input cavity is threaded with described first connector away from one end of described output cavity, the two ends of described output cavity are threaded with described second connector respectively, and described first connector, the junction of described second connector and described cavity is provided with rubber gasket, described first connector is circular, described second connector is square.
Be different from the situation of prior art, the invention has the beneficial effects as follows: standing-wave ratio can be made to meet multiple frequency range by stairstepping standing wave matching structure simultaneously, thus can frequency coverage be improved, meeting high-power while, also can meet the covering to wide band signals, reduce the wastage simultaneously.
Accompanying drawing explanation
Fig. 1 is the principle schematic of embodiment of the present invention power splitter.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, it is the principle schematic of embodiment of the present invention power splitter.The power splitter of the present embodiment comprises the first connector 1, second connector 2 and cavity 3.Cavity 3 comprises integrated output cavity 31 and input cavity 32, output cavity 31 is vertically connected with input cavity 32, input cavity 32 is provided with multiple installing hole 321, away from the side of input cavity 32, there is the stairstepping standing wave matching structure 310 concaved at output cavity 31, stairstepping standing wave matching structure 310 comprises three grades of ladders, the height sum of three grades of ladders is 1/4 λ, and the width sum of three grades of ladders is λ.Input cavity 32 is threaded with the first connector 1 away from one end of output cavity 31, the two ends of output cavity 31 are threaded with the second connector 2 respectively, and the first connector 1, second connector 2 is provided with rubber gasket 4 with the junction of cavity 3, first connector 1 is circular, and the second connector 2 is square.
Wherein, installing hole 321 is blind hole, and installing hole 321 is conducive to stability when installing.The cross section of input cavity 32 and output cavity 31 can be square, also can be circular.
Power splitter of the present invention adopts stairstepping standing wave matching structure 310, and object is to utilize these three grades of ladders to realize multistage coupling, meets multiple frequency range to make standing-wave ratio simultaneously.
The power splitter of the embodiment of the present invention can make standing-wave ratio meet multiple frequency range by stairstepping standing wave matching structure simultaneously, thus can improve frequency coverage, also can meet the covering to wide band signals, reduce the wastage simultaneously meeting high-power while.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
