The utility model is characterized in that through holes corresponding to the coaxial connectors are formed on the housing and the conductor in the housing, the inner cores of the coaxial connectors are directly connected with the through holes in an assembled manner, a part of the conductor in the housing and a part of the inner core of the connector are designed to be mechanically matched with each other so that the conductor and the inner core can be connected in an assembled manner, and different power distribution ratios can be achieved by adjusting the conductor in the housing. The utility model has the advantages of small volume, light weight, low cost and simple manufacturing process, and is worth of popularization.
Description
Technical field
The utility model product relates to the passive communication equipment technical field, specifically a kind of inside mounting structure of power division.
Background technology
The main effect of power divider in microwave system (abbreviation power splitter) is: the microwave input power on a certain road is divided into two-way or multichannel output to scale; Perhaps two-way or multi-channel microwave power are stacked up from one tunnel output.Single device power division has simultaneously with synthetic these the two kinds of opposite functions of power, and this class device main technical requirements is: each input/output port must mate, and power output is distributed to scale.Tradition T type power divider is a reversible three-port network that does not have consumption, each port can not realize simultaneously mating and the power division port between mutual isolation, if, then can satisfy simultaneously and isolate and the coupling requirement if resistance element is suitably regulated in network.
Summary of the invention
The purpose of this utility model is exactly that a kind of not only mechanical processing technique that provides for the deficiency that solves prior art is simple, easy to assembly, volume is little, in light weight, and the low broadband cavity power splitter of cost.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of broadband cavity power splitter, the conductor that comprises housing and interior setting thereof, the input port and the output port of housing are provided with coaxial connector, it is characterized in that: described housing and inner conductor thereof are provided with the through hole corresponding with coaxial connector, and the coaxial connector inner core directly assembles with through hole and is connected.
Described enclosure interior conductor and connector inner core partly adopt the design of coupling machining, and coaxial connector adopts conductor ring flange separate structure.
Described power splitter frequency range is 600MHz-3800MHz, and the enclosure interior conductor does not evenly have the cascade of consumption transmission line by plurality of sections to be formed, and the length of each line segment all is 1/4 wavelength of centre frequency.
Described housing is hollow cuboid.
Mechanical tapping is adopted in the junction of described enclosure interior conductor and coaxial connector, and the coaxial connector inner core adopts corresponding helicitic texture.
The input port of described housing is provided with 1 coaxial connector, and the output port of housing connects 2 relative up and down coaxial connectors, constitutes two power splitters.
The input port of described housing is provided with 1 coaxial connector, and the output port of housing connects 3 coaxial connectors, constitutes three power splitters.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
1, the utility model adopt is connected between coaxial connector inner core and the enclosure interior conductor adopt machining after assembling realize that direct connection has the advantage of bandwidth, and device is influenced less under physics and environmental factor.
2, device manufacturing process is oversimplified, light littleization of equipment, the purpose that equipment cost is low.
