Embodiment
As shown in Figure 1, comprise coupling cavity 5, the input 1 be communicated with coupling cavity 5, output terminals A 2, output B3, isolation end 4.Input 1 and isolation end 4 are positioned at the front end face of coupling cavity 5, and output B3 and output terminals A 2 are positioned at the rear end face of coupling cavity 5, and front end face and rear end face are coupling cavity two end faces in opposition to each other.Isolation end 4 is positioned at the right side of input 1, and output B3 is positioned at output terminals A 2 right sides.In coupling cavity 5, be provided with 5 rectangles add carrier 6 and 2 circles add carrier 6, add carrier 6 for axis column in the vertical direction.The carrier 6 that adds of rectangle does not overlap along the sagittal axis of input 1; The described carrier 6 that adds is connected with upper inwall or the lower inwall of coupling cavity 5.The right flank width of described coupling cavity 5 has 2 variations along the axis direction of input 1.The concrete lower medial surface that is changed to coupling cavity 5 is provided with metal bump, and the protrusion direction of metal bump is pointed in coupling cavity 5.
Adjacent the adding between carrier 6 of arranging along input 1 front and back to axis direction exists difference in height and or stand out.Input 1, output terminals A 2, output B3, isolation end 4 all are connected with coupling cavity 5 by one section matched waveguide 7.
The upper surface of the upper surface of the upper surface of the upper surface of the upper surface of the upper surface of input 1, output terminals A 2, output B3, isolation end 4, coupling cavity 5, matched waveguide 7 all is positioned at same plane.
Adding carrier 6 is rectangle or circle at the cross section of overlooking on direction, and coupling cavity 5, input 1, output terminals A 2, output B3, isolation end 4 are cuboid.
There is zero clearance before the direction adjacent load body vertical to axis direction with the front and back of input 16, and add carrier 6 for metal column or be the medium post.Adding in the present embodiment carrier 6 selects metal column that metal material makes as the preferred version that adds carrier 6.Adding carrier 6 can also be the medium post simultaneously.
The input 1 of rectangle has mainly encouraged two waveguide mode of operations, i.e. TE10 pattern and TE20 pattern in the coupling cavity 5 of rectangle.The ripple of these two patterns all will be propagated to axis direction along input 1 front and back.Due to the guide wavelength difference of these two patterns, at the other end of coupling cavity 5, the power that output terminals A 2 and output B3 place are coupled out from coupling cavity 5 be the power that is coupled out from the ripple of two mode of operation TE10 patterns and TE20 pattern respectively and.By width and the length of choosing coupling cavity 5, and the size of each input/output terminal and position, can make the power sum that output B3 is coupled out from two mode of operations respectively meet certain designing requirement, it is 180 degree that the power phases that simultaneously makes isolation end 4 be coupled out from two mode of operations respectively differs, and cancels out each other.At this moment, all energy are all exported from output terminals A 2 and output B3 basically, and not from input 1 reflection, also from isolation end 4 outputs.In order further to widen the bandwidth of operation of device, the shape of coupling cavity 5, particularly width can suitably change along the axis of input, especially at bottom or the top of coupling cavity 5, add carrier 6.Each input/output terminal can increase one or more levels ridge waveguide matched waveguide 7.
