[embodiment]
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
With reference to Fig. 1, Fig. 2, Fig. 3, as shown be bidirectional coupled apparatus with two coupling by-passes, the axial shape of coupling by-pass is respectively cylindric and rectangular-shaped, all there is cavity on the two sides on the coupling device shell, be coupling cavity 3 and the cavity 12 of placing the coupling circuit plate, coupling cavity 3 and cavity 12 are in the corresponding setting in the both sides of coupling device shell, and wherein 8 are coupling main line (also can be called mobile jib), and there are coupling by-pass (or the secondary bar that is coupled) 9 and coupling by-pass 10 in its both sides.Coupling main line 8, coupling by-pass 9 and coupling by-pass 10 are metallic conductor, as long as the shape of coupling cavity 3 guarantees to install coupling main line 8 and the corresponding coupling by-pass 9 and 10 that is provided with, do not have specific (special) requirements for shape.Port one and port 2 are coupling main line signal input output end mouth, and the direction of its input and output can be exchanged, and is promptly described two-way.Radiofrequency signal is imported from port one,, also can be exported by port one through the coupling main line through port 2 inputs to port 2 outputs through the coupling main line.Present embodiment is imported from port one with coupled signal, is output as example from port 2.Main signal is from the port one input of coupling main line 8 inputs, port 2 outputs from coupling main line 8 outputs, in this process, article two, coupling by-pass 9 and 10 is coupled out a part of signal component from coupling main line 8, i.e. coupling amount, by cylindrical conductor 4,5,6,7 fixing respectively on the coupling by-pass 9 and 10 the coupling amount is drawn out on the coupling circuit plate, behind the connection in series-parallel resistor trimming on the overcoupled circuits plate, exports each monitoring port to.By the distance between adjustment coupling main line 8 and the coupling by-pass 9 and 10, can adjust the size of coupling amount, usually, be coupled main line 8 and two distances that are coupled between the by-pass 9 and 10 have just been determined well when assembling; By series-parallel resistance on the coupling circuit plate, can finely tune the degree of coupling and isolation.
Between the cavity of coupling main line 8 and coupling cavity 3, it is fixing to make medium screw 12,13,14,15 main line 8 that will be coupled by the material of 4 polytetrafluoroethylene, and the cavity inner wall of will be coupled main line 8 and coupling cavity 3 insulate.Equally, the conductor column of every coupling on the by-pass all adds the hollow medium cover that a polytetrafluoroethylmaterial material is made outward, can realize being coupled by-pass 9 and 10 and the insulation of the cavity inner wall of coupling cavity 3, and 16,17,18,19 are the hollow medium cover among the figure.Certainly, the material of medium screw and hollow medium cover has more than and is limited to polytetrafluoroethylmaterial material, also comprises other the material with above-mentioned insulation function.
