One, microstrip design, its limited bandwidth, general being difficult to above four times of frequencys multiplication;
Two, band line cavity design, face too limit bandwidth, the frequency that be difficult to surpass 700-2700MHz, in case and bandwidth widen, the band line lengthens, rigidity with line just is difficult to guarantee, very easily distortion, the product of actual trial-production and the difference of emulation are huge, are difficult to practicality, because the coupled zone of electric bridge is tight especially, thus the design that causes electric bridge always the coupler of different frequency want the many of difficulty;
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, has limited greatly the application of this series products.
The utility model content:
The purpose of this utility model provides a kind of Pyatyi microstrip line electric bridge, it has adopted coupled striplines Pyatyi microstrip line symmetric design, not only can satisfy general column coupling bar electric bridge for the requirement that covers bandwidth, it is long and can't guarantee rigidity to have changed simultaneously the band line, yielding situation, and reduced processing request precision, matching requirements and the production cost in the production process.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is by cavity, cover plate, wiring board, dielectric-slab, the additional agents plate consists of, the cavity top is equipped with cover plate, be provided with wiring board in the cavity, the upper and lower surface of wiring board is respectively arranged with a microstrip line, four ends of microstrip line all can be 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 the additional agents plate, described microstrip line is all by the one-level coupled zone, the secondary coupled zone, three grade coupled districts, the quadrupole district, the Pyatyi coupled zone consists of, 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 respectively that quadrupole district and Pyatyi coupled zone also are centrosymmetric structures.
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 utility model is the wiring board that is 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 the one-level coupled zone, the secondary coupled zone, three grade coupled districts, the quadrupole district, the Pyatyi coupled zone consists of, skin at the upper and lower medium plate of position, one-level coupled zone is provided with the additional agents plate, four ends of microstrip line all can be connected with outside by cavity, that wherein be connected with the quadrupole district of a microstrip line is input port I, that be connected with the 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 the quadrupole district is output port II, when microwave signal enters from input port I or input port II, the signal of half is just exported from output port I, second half signal is exported from output port II, so just finished the mean allocation task of power, because adopt the Pyatyi microstrip design, so that the bandwidth of electric bridge is wider, can cover 350-2700MHz, the skin of while at the upper and lower medium plate of position, microstrip line one-level coupled zone is provided with the additional agents plate, enlarged the coupling distance of one-level coupled zone, thereby be easy to so that microstrip line is accomplished on a wiring board, avoid that whole upper and lower medium plates thickeies all that 5mm causes two, three, four, the appearance of the situation that Pyatyi is wide and failed.
The utility model has adopted coupled striplines Pyatyi microstrip line symmetric design, not only can satisfy general column coupling bar electric bridge for the requirement that covers bandwidth, it is long and can't guarantee rigidity to have changed simultaneously the band line, yielding situation, and reduced processing request precision, matching requirements and the production cost in the production process.
