Abstract
The utility model relates to a miniaturization high-power 3dB directional coupler, which comprises a broadside coupled strip line (1) and fixing pieces (2), wherein the left side and the right side of the broadside coupled strip line (1) are symmetrical, the broadside coupled strip line (1) is provided with continuous arc bends, and the fixing pieces (2) are arranged at two ends of the broadside coupled strip line (1). According to the utility model, the place which needs to be bended adopts the arc bend for replacing original tangential angle with 45 degrees, therefore, arc bend can be continuously arranged for improving the compact degree and reducing the area of domain territory, thus the volume and weight can be greatly reduced, i.e. the cost of an antenna system can be greatly reduced, and the maneuver performance and the reliability can be greatly improved.
Description
Technical field
The utility model relates to a kind of coupler, relates in particular to the high-power 3dB directional coupler of a kind of miniaturization.
Background technology
In high-power broadside coupled strip line 3dB directional coupler, the principal element that influences anti-power has: material interfaces such as perpendicular interconnection and pin; The discontinuous place of broadside coupled strip line (turn round, corner cut etc.).
Traditional processing mode of turning round is 45 ° of corner cuts, and such processing mode can cause the bottleneck of anti-power, causes the volume of whole directional coupler compact inadequately.
The utility model content
Technical problem to be solved:
Provide a kind of size of high-power broadside coupled strip line directional coupler of can further dwindling to satisfy the light-weighted requirement of microwave system (as radar and communication system etc.) miniaturization at above not enough the utility model.
Technical scheme:
The high-power 3dB directional coupler of a kind of miniaturization comprises broadside coupled strip line and fixture; Broadside coupled strip line left-right symmetric, and be provided with continuous circular arc and turn round, anchor designs is at the two ends of broadside coupled strip line.
Beneficial effect:
The broadside coupled strip line of structural design of the present utility model needs corner to adopt circular arc to turn round and replaces former 45 ° of corner cuts.Can be provided with continuously like this and turn round, with the compact degree of raising domain, the scaled down version area of pictural surface, thus volume weight can be dwindled significantly, mean that the cost of this antenna system can reduce significantly, and mobility and reliability can increase substantially.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
As shown in Figure 1, the high-power 3dB directional coupler of this miniaturization comprises broadside coupled strip line 1 and fixture 2; Broadside coupled strip line 1 left-right symmetric, and be provided with continuous circular arc and turn round, fixture 2 designs are at the two ends of broadside coupled strip line 1.
Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly be familiar with this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection range of the present utility model should be defined with the application's claim protection range is as the criterion.
Claims (1)
1. the high-power 3dB directional coupler of miniaturization is characterized in that: comprise broadside coupled strip line (1) and fixture (2); Broadside coupled strip line (1) left-right symmetric, and be provided with continuous circular arc and turn round, fixture (2) design is at the two ends of broadside coupled strip line (1).
