The invention discloses a five-stage coupling bridge, and relates to the technical field of bridges. The five-stage coupling bridge is composed of a cavity, a cover plate, dielectric plates and additional dielectric plates, wherein the cover plate is installed above the cavity, the cavity is internally provided with the circuit board, the upper surface and the lower surface of the circuit board are provided with a microstrip line respectively, four ends of the microstrip lines are connected with the external part through the cavity, the dielectric plates are arranged above and below the circuit board respectively, and the dielectric plates are externally provided with the additional dielectric plates respectively. The five-stage coupling plate adopts a coupling strip line five-stage microstrip line symmetric design, not only can meet requirements of general columnar coupling rod bridges for the bandwidth and change a circumstance that the strip lines cannot be guaranteed in rigidity and easy to deform because the strip lines are too long at the same time, but also reduces the required processing accuracy, assembling requirements and the production cost in the production process.
Description
Technical field:
The present invention relates to bridge technology field, particularly relate to a kind of Pyatyi coupling electric bridge.
Background technology:
The frequency of now widely used 3dB electric bridge is between 800-2500MHz, this frequency covers the main frequency of mobile communication, also contemplated the universal frequency of 3G simultaneously, due to popularizing of Digital Television, the frequency that original analog signal cancels 700MHz gradually is probably used on the product of 3G, if want entirely to be with covering, just need electric bridge, power splitter that bandwidth is wider, can cover more frequency range like this, existing electric bridge generally adopts following several design, but has respective defect:
One, microstrip design, its limited bandwidth, is generally difficult to more than four times of frequencys multiplication;
Two, line cavity design is with, face bandwidth restriction too, be difficult to the frequency more than 700-2700MHz, and once bandwidth is widened, band line lengthens, rigidity with line is just difficult to ensure, very easily be out of shape, the difference of the product that reality is manufactured experimently and emulation is huge, is difficult to practicality, because the coupled zone of electric bridge is tight especially, so cause the coupler of the design of electric bridge different frequency always to want difficulty many;
Three, column coupling bar design, although its bandwidth can cover 350-2700MHz, its processing request precision is high, and assembling is complicated, and cost is high, significantly limit the application of this series products.
Summary of the invention:
The object of this invention is to provide a kind of Pyatyi coupling electric bridge, it have employed coupled striplines Pyatyi microstrip line symmetric design, not only can meet general column coupling bar electric bridge for the requirement covering bandwidth, change simultaneously and be with line long and rigidity cannot be ensured, yielding situation, and reduce processing request precision in production process, matching requirements and production cost.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it is by cavity, cover plate, wiring board, dielectric-slab, additional agents plate is formed, above cavity, cover plate is installed, wiring board is provided with in cavity, the upper and lower surface of wiring board is respectively arranged with a microstrip line, four ends of microstrip line are all connected with outside by cavity, the upper and lower of wiring board is respectively arranged with dielectric-slab, the outside of dielectric-slab is respectively arranged with additional agents plate, described microstrip line is all by one-level coupled zone, secondary coupled zone, three grade coupled districts, quadrupole district, Pyatyi coupled zone is formed, look from depression angle, article two, the one-level coupled zone of microstrip line overlaps, the both sides of one-level coupled zone are respectively secondary coupled zone and three grade coupled districts, centered by symmetrical structure, the outside in secondary coupled zone and three grade coupled districts is quadrupole district and Pyatyi coupled zone respectively is also centrosymmetric structure.
Described additional agents plate is arranged on the skin of the upper and lower medium plate of position, microstrip line one-level coupled zone.
The length and width of described additional agents plate, thick difference can change in the scope of 28-34mm, 16-24mm, 4.5-5.5mm.
Described dielectric-slab thickness is 5mm.
The present invention is the wiring board being provided with microstrip line in cavity and cover plate, the upper and lower of wiring board is respectively arranged with dielectric-slab, microstrip line is all by one-level coupled zone, secondary coupled zone, three grade coupled districts, quadrupole district, Pyatyi coupled zone is formed, the skin of the upper and lower medium plate of position, one-level coupled zone is provided with additional agents plate, four ends of microstrip line are all connected with outside by cavity, that be wherein connected with the quadrupole district of a microstrip line is input port I, that be connected with Pyatyi coupled zone is output port I, that be connected with the Pyatyi coupled zone of another microstrip line is input port II, that be connected with quadrupole district is output port II, when microwave signal enters from input port I or input port II, the signal of half just exports from output port I, second half signal exports from output port II, this completes the mean allocation task of power, because adopt Pyatyi microstrip design, make the bandwidth of electric bridge wider, 350-2700MHz can be covered, on the skin of the upper and lower medium plate of position, microstrip line one-level coupled zone, be provided with additional agents plate simultaneously, expand the coupling distance of one-level coupled zone, thus be easy to make microstrip line accomplished on a wiring board, avoiding whole upper and lower medium plates all to thicken, 5mm causes two, three, four, wide and the appearance of the situation of failure of Pyatyi.
Present invention employs coupled striplines Pyatyi microstrip line symmetric design, not only can meet general column coupling bar electric bridge for the requirement covering bandwidth, change simultaneously and be with line long and rigidity cannot be ensured, yielding situation, and reduce processing request precision in production process, matching requirements and production cost.
