Description
Technical field
The present invention relates to a kind of power splitter, specifically, relate to a kind of magic T power splitter based on novel matching structure.
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.
Summary of the invention
The object of the present invention is to provide a kind of magic T power splitter simple, that isolation is good of processing.
To achieve these goals; The technical scheme that the present invention adopts is following: a kind of magic T power splitter based on novel matching structure; 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 it is inner that matching structure partly extends into the second output rectangular waveguide, and 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.
Based on said structure; Among the present invention; General with the second output rectangular waveguide during as input; It is inner that matching structure among the present invention partly extends into the second output rectangular waveguide, and in order to mate the shape of the second output rectangular waveguide, so matching structure is made up of at least two rectangle steps and a metal column.
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 present invention 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 second output rectangular waveguide is provided with the 4th output port away from an end of matching structure.
The 4th output port is an isolated port.
The material of described matching structure is a metal.
Principle of the present invention is: the operation principle according to magic T can be known.
Will be among the present invention from the H face input of the first output rectangular waveguide.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.
Beneficial effect of the present invention 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; And phase place and amplitude balance degree at output port are fine, and good isolation is arranged between the isolated port.
