Lange coupler bridle wire structure and implementing method

Abstract

The invention relates to a jumper structure of a Lange coupler, which substantially comprises an input port, a throughway port, a coupling port and an isolate port. The input port, the throughway port, the coupling port and the isolate port are respectively connected with a copper wire; a jumper used for connecting is arranged between the copper wires; a bonding pad is arranged at the joint of the jumper and the copper wire. The Lange coupler jumper can be realized by the following method and steps: a printed plate is arranged according to the junction of the input port, the throughway port, the coupling port and the isolate port and is assembled in a circuit box; the bonding pad is arranged at the positions where the jumper is required, the jumper is welded on a circuit printed board by an electric iron. The jumper structure has the advantages that the adoption of the copper wire taking the place of a spun gold and the bonding pad jumper structure can realize the Lange coupler manufactured by an ordinary printed plate process, which gains better effect; the jumper also has the advantages of excellent electrical properties, simple structure, simple implement method, comparatively small volume, good anti-vibration effect and good high and low temperature indexes and so on.

Description

technical field [0001] The invention relates to the field of couplers, and mainly relates to a Lange coupler jumper structure and a realization method. Background technique [0002] The Lange coupler is a classic implementation of tightly coupled microstrip circuits, and it has the advantages of wide frequency bandwidth, small phase error, high directivity and low standing wave ratio. The usual practice is to weld a gold wire jumper with a gold wire pressure welding machine, which is difficult to achieve in civilian use. Mainly reflected in: firstly, the cost of the gold wire bonding machine and gold wire used is relatively high, and the printed board needs to be specially treated, so that the market competitiveness of the product is not enough; secondly, the training requirements for assemblers are relatively high , which is not conducive to mass and rapid production; finally, the gold wire is easy to fall off or loose after being collided, which poses a risk to ensure dev...
