The technical solution adopted for the present invention to solve the technical problems: an a kind of four strip line splitter comprises: two microwave base plates, two metal ground plates, one are interconnected one minute four power divider circuit that forms by three bridge-type minor matters hybrid couplers; One minute four power divider circuit is arranged on the face of two faces of a microwave base plate wherein, another surface is metal ground plate; There is not any attachment for metal ground plate, another side on the face in two faces of another piece microwave base plate; Two microwave base plate shapes are identical, and area is identical, stack face-to-face, and one minute four power divider circuit is clipped in the middle, and two metal ground plates are exposed; Two microwave base plates, two metal ground plates, one fen four power divider circuit stack as a whole by the external force extruding.
The preparation method of one four strip line splitter is as follows:
(1) on the wherein one side of a two-sided microwave copper-clad base plate, obtain desired one and interconnect one minute four power divider circuit that forms by three minor matters bridge-type hybrid couplers, it is metal ground plate that the critical piece of this one minute four power divider circuit one four strip line splitter, the another side of retention substrate cover copper;
(2) one side of the two-sided microwave copper-clad base plate that another is identical shaped and big or small is covered copper corrosion and is fallen, and keeping another side is another metal ground plate;
(3) two microwave base plates that the shape that processes is identical, area is the same are stacked together, and guarantee that one minute four power divider circuit is clipped in the middle, use external force to make described two microwave base plates and one minute four power divider circuit push to stack as a whole, between do not stay the slit.
Described step (1) adopts the method for photomechanical process or photoetching corrosion on the wherein one side of two-sided microwave copper-clad plate, obtains desired one minute four power divider circuit.
The caustic solution of described step (2) adopts copper-clad plate acid liquid corrosion method.
The advantage that the present invention is compared with prior art had: the present invention is by the feature performance benefit of three bridge-type minor matters hybrid couplers, and design realization with strip line, it is little, simple in structure to have reached strip line power splitter volume, the advantage that is easy to process, simultaneously also obtain the impedance bandwidth of broad, less energy loss, realized the miniaturization of power splitter.The present invention can reach 30% relative bandwidth, and power loss＜0.4dB can realize being widely used in the power division of four port five equilibriums, non-five equilibrium, arbitrary proportion in the radio frequency microwave system.
