Abstract
The utility model discloses a four-in-four-out broadband bridge which comprises a bridge box and eight joints. The bridge box is composed of a base, an inner cover plate and an outer cover plate, and is in a square structure. The inner cover plate is fixed on the base. The outer cover plate is fixed outside the inner cover plate. Eight joints are divided into four groups which are located on four sides of the bridge box, wherein each group comprises two joints. A cavity is arranged in the base. Four broadband lines are arranged in the cavity. According to four broadband lines, both ends are respectively connected with the joints to form the four-in-four-out broadband bridge. Four broadband lines are distributed in a layered manner. The broadband lines are isolated by insulators. The four-in-four-out broadband bridge provided by the utility model has great three order intermodulation, generally can reach -150dBc, can reach -160dBc when highly required, and has the advantages of large loaded power, small insertion loss, simple assembly and debugging and the like.
Description
Technical field
The utility model relates to broadband electric bridge.
Background technology
What at present, prior art was used is micro-band and Stripline hybrid common or that be stitched together.That micro-band electric bridge can't carry is high-power, Insertion Loss is large, third order intermodulation is poor, the wiring board precision is not high; Common Stripline hybrid third order intermodulation is poor, and the Stripline hybrid debugging be stitched together is difficult, cost is high.
Summary of the invention
Problem to be solved in the utility model is that a kind of third order intermodulation of design is good, load power is large and four advances four and go out electric bridge.
For addressing the above problem, the scheme that the utility model adopts is as follows:
A kind of four advance four broadband electric bridges that go out, and comprise electric bridge box and 8 joints; The electric bridge box is comprised of base, inner cover plate, outer cover plate, is cube structure, and inner cover plate is fixed on base, and outer cover plate is fixed on outside inner cover plate; 8 joints divide four groups, every group of 2 four sides that are positioned at the electric bridge box; Cavity is arranged in base, in cavity, be provided with 4 broadband line; Four broadband electric bridges that go out are advanced at the two ends of 4 broadband line jointing formation four respectively; Four broadband line layered arrangement, isolate with insulator between broadband line and broadband line.Wherein, between described broadband line and joint, the mode by welding is connected.Described joint is pressed into the electric bridge box by the mode of pressing, and is screwed.Described base, inner cover plate, outer cover plate are screwed.
Further, between described inner cover plate and base, sealing strip can also be set.
Technique effect of the present utility model: it is good to the utlity model has third order intermodulation, generally can reach-150dBc, requires more Gao Shikeda-160dBc; Load power is large; The advantages such as Insertion Loss is little, and assembling and setting is simple.
The accompanying drawing explanation
The structural representation of Fig. 1 utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further details.
A kind of four advance four broadband electric bridges that go out, and as shown in Figure 1, comprise electric bridge box 1 and 8 joints.8 joints are labeled as respectively joint 21, joint 22, joint 23, joint 24, joint 25, joint 26, joint 27 and joint 28.Electric bridge box 1 is comprised of base 3, inner cover plate 4, outer cover plate 5.Electric bridge box 1 is cube structure, and inner cover plate 4 is fixed on base 3, and outer cover plate 5 is fixed on outside inner cover plate 4.8 joints divide four groups, every group of 2 four sides that are positioned at electric bridge box 1, specifically, joint 21, joint 22 are positioned at the one side of electric bridge box 1, joint 23, joint 24 are positioned at the one side of electric bridge box 1, and joint 25, joint 26 are positioned at the one side of electric bridge box 1, and joint 27, joint 28 are positioned at the one side of electric bridge box 1.Cavity 31 is arranged in base 3, in cavity 31, be provided with 4 broadband line 32.Four broadband electric bridges that go out are advanced at the two ends of 4 broadband line 32 jointing formation four respectively, specifically, joint 21 is connected with joint 27 by broadband line 32, joint 22 is connected with joint 28 by broadband line 32, joint 23 is connected with joint 25 by broadband line 32, and joint 24 is connected with joint 26 by broadband line 32.Mode by welding between broadband line 32 and joint is connected.Four broadband line 32 are layered arrangement in cavity 31, with insulator 33, isolate between broadband line 32 and broadband line 32.Joint is pressed into electric bridge box 1 by the mode of pressing, and fixing with screw 11.Base 3, inner cover plate 4, outer cover plate 5 are also fixing by screw 11.Between inner cover plate 4 and base 3, sealing strip 6 can also be set, be used to guaranteeing inner sealing property.
