Abstract
The utility model discloses a rectangular waveguide combiner with increased bandwidth and high power capacity. The rectangular waveguide is a pipeline which is formed by the enclosing of two parallel H sides and two parallel E sides and has a rectangular cross section. In the combiner, two panels parallel to the two H sides are arranged between the two H sides; the two panels are spaced with a certain distance to form a coupling window; an input end, an isolation end, an output end and a coupling end are formed on the left upper side, the left lower side, the right upper side and the right lower side of the coupling window respectively; a stepped pit is formed on each H side; and a boss is arranged on the E side corresponding to the center of the coupling window and is arranged to face the center.
Description
Technical field
The utility model relates to the technical field of microwave communication, relates to a kind of mixer of rectangular waveguide particularly.
Background technology
As shown in Figure 1, rectangular waveguide is that the cross section that is surrounded by two H faces that are parallel to each other, two E faces that are parallel to each other is the pipeline of rectangle, and mixer is to be provided with two flat boards in parallel in the centre of two H faces; Two flat boards keep at a certain distance away and form coupling window; Coupling window upper left side, left downside, upper right side, lower right side are respectively input, isolation end, output, coupled end, add the allotment screw in the center of coupling window, work to widen working band, reduce standing wave, increase at a distance from isolating; But along with the allotment screw gos deep in the waveguide; The distance of the E face of the top end face of screw and waveguide reduces, and electric field therebetween also can increase thereupon, when high-power applications; Too high field intensity can cause the interior air of waveguide by ionization puncture, the disabler of device.
Summary of the invention
The technical problem that the utility model will solve provides the mixer of the rectangular waveguide that a kind of bandwidth increases, power capacity is big.
The technical scheme that addresses the above problem is: the mixer of this rectangular waveguide; Rectangular waveguide is that the cross section that is surrounded by two H faces that are parallel to each other, two E faces that are parallel to each other is the pipeline of rectangle; Mixer is to be provided with two flat boards in parallel in the centre of two H faces; Two flat boards keep at a certain distance away and form coupling window, and the upper left side of coupling window, left downside, upper right side, lower right side are respectively input, isolation end, output, coupled end, are provided with stepped recessed at the H face; Upright on the E face corresponding with the center of coupling window have convex, and convex is towards this center.
Stepped recessed owing to being provided with at the H face, so reduced the reflection of electromagnetic transmission, effectively increased bandwidth; Stepped recessed on adjusting through the convex height on the E face and the H face makes that the power capacity of mixer is big.
Description of drawings
Fig. 1 is the vertical view that removes an E face of the mixer of traditional rectangular waveguide;
Fig. 2 is the vertical view that removes an E face according to the mixer of the rectangular waveguide of the utility model.
Embodiment
As shown in Figure 2; The mixer of this rectangular waveguide, rectangular waveguide are to be the pipeline of rectangle by two H faces that are parallel to each other 1, two cross sections that the E face that is parallel to each other (not shown, parallel with paper plane) surrounds; Mixer is to be provided with two flat boards 2 in parallel in the centre of two H faces 1; Two flat boards 2 keep at a certain distance away and form coupling window 5, and the upper left side of coupling window 5, left downside, upper right side, lower right side are respectively input, isolation end, output, coupled end, are provided with stepped recessed 11 at the H face; Upright on the E face corresponding with the center of coupling window 5 have convex 4, and convex 4 is towards this center.
Preferably, said convex 4 has cylindroid shape.
Preferably, said stepped be shape with three grades of steps.
The mixer of this rectangular waveguide; Waveguide mixer structure to traditional improves, and mainly is to have added the step conversion in the both sides of H face coupling window and removed the allotment screw in the waveguide, and step is used for mating fully standing wave and increases coupling energy; Allotment screw originally removes; Directly in waveguide, process oval convex, because the matching effect of step makes the convex of waveguide reduce height; Through the size of adjustment step, coupling window width and convex, realize the requirement of high power, low Insertion Loss, high isolation, low standing wave.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs to the protection range of the utility model technical scheme to any simple modification, equivalent variations and modification that above embodiment did.
