Technical field
The utility model relates to a kind of power splitter, specifically, relates to novel compact type waveguide evil spirit T power splitter.
Background technology
Power divider and synthesizer are the significant components in the microwave system, be used for transmit power allocation is gone to different loads, or different power is combined into one the tunnel, to obtain bigger power.Indexs such as the performance of microwave power divider such as Insertion Loss, isolation, phase equilibrium degree and amplitude balance degree will produce material impact to the performance of whole system.Common power divider is the distributed constant power splitter that adopts microstrip line or cavity waveguide at present.Cavity waveguide power divider Insertion Loss is little, and it is relatively poor that good but its shortcoming of amplitude balance degree is an isolation, the manufacture craft more complicated.
The utility model content
The purpose of the utility model is to provide a kind of and processes simply, isolation is good and the magic T power splitter of compact conformation.
To achieve these goals; The technical scheme that the utility model adopts is following: novel compact type waveguide evil spirit T power splitter; Mainly exporting rectangular waveguide and the input rectangular waveguide that is connected with the first output rectangular waveguide respectively and the second output rectangular waveguide by first constitutes; The said first output rectangular waveguide set inside has matching structure; And matching structure partly extends into the second output rectangular waveguide; Said matching structure mainly is made up of with the metal column that rectangle step end face is connected with a bottom surface at least two rectangle steps that connect successively, and second output waveguide is spent to 90 degree around the axis direction bending 0 of input waveguide away from an end of matching structure, and the second output waveguide bending part is provided with absorbing material.
Second output waveguide is spent around the axis direction bending 90 of input waveguide away from an end of matching structure.
The axis of the axis of the axis of the first output rectangular waveguide, input rectangular waveguide, the second output rectangular waveguide is orthogonal in twos, the axis of the second output rectangular waveguide and the parallel axes of metal column.
Based on foregoing; The utility model is arranged to the mutually perpendicular structure of structure axis in the mutually perpendicular in twos three dimensions with the axis of the first output rectangular waveguide, the axis of input rectangular waveguide, the axis of the second output rectangular waveguide; Can solve the good problem of amplitude balance degree; The matching structure of set inside can effectively guarantee the problem of isolation simultaneously, and in order to be effective optimization, matching structure adopts disposable milling to process.
It is symmetrical with respect to input rectangular waveguide axis that all form the rectangle step and the metal column of matching structure, and all rectangle steps successively decrease along the axis of width edge second output waveguide of input rectangular waveguide axis direction from the bottom up successively; The rectangle step successively decreases along the axis of width edge second output waveguide of the first output waveguide axis direction from the bottom up successively.
The bottom of forming the metal column of matching structure is connected with the end face of rectangle step, and metal column is along the length of the length of importing the rectangular waveguide direction less than connection rectangle step.
The two ends of the first output rectangular waveguide are respectively arranged with second output port and the 3rd output port.
The material of described matching structure is a metal.
In the utility model; Because the second output rectangular waveguide will mate with load and be connected, and owing to the general second output rectangular waveguide with after load is connected, the volume of whole power splitter can increase; Therefore in the utility model; The spy spends the second output rectangular waveguide to 90 degree around the axis direction crooked 0 of first output waveguide away from an end of matching structure, and the volume that reduces the utility model that can be an amount of is learnt according to actual design; When the second output rectangular waveguide away from an end of matching structure when the axis direction crooked 90 of first output waveguide is spent, the volume of the power splitter of the utility model design is minimum.Like this second output rectangular waveguide is carried out bending; Because the axis of the axis of the first output rectangular waveguide in the utility model, the axis of input rectangular waveguide, the second output rectangular waveguide is arranged to mutually perpendicular in twos; Therefore spatially the height of the axis direction of first output waveguide is constant; Therefore in order to reduce volume, be about to the second output rectangular waveguide and carry out bending setting, can make the volume of the second output rectangular waveguide axis direction reduce.To reach the purpose that reduces the power splitter volume.The miniaturization Design that helps power splitter.
The principle of the utility model is: the operation principle according to magic T can know,
To import from the H face of the first output rectangular waveguide in the utility model.When signal is imported by the port of input rectangular waveguide; The 4th output port is an isolated port; Second output port and the 3rd output port are accomplished the output of constant amplitude homophase, put into some matching elements in magic T inside, and the reflection that its discontinuity that produces reflection and magic T is produced makes each port match.
The second output waveguide novel compact type partly is provided with absorbing material, absorbs the electromagnetic wave that gets into second output waveguide.
The beneficial effect of the utility model is; Processing is simple, and matching structure and magic T just can process through disposable milling, has reduced the rigging error when the assembling matching result; Second output waveguide is spent around the axis direction novel compact type 90 of input waveguide away from an end of matching structure; Make the structure of power splitter compact more, and fine at the phase place and the amplitude balance degree of output port, good isolation is arranged between the isolated port.
