Problems solved by technology

The material is soft, easy to deform, and greatly affected by the ambient temperature, which affects the stability of the microwave coupler operation
In addition, when the insulating parts of this material are processed, the blank needs to be pressed first and then machined into shape. The processing procedure is complicated and the processing cost is relatively high.

Abstract

The invention relates to a passive device used in a microwave communication device, in particular to a microwave coupler. The microwave coupler comprises a shell body with cavity, the shell body cavity is arranged with a master signal line and a coupling signal line side by side, the outer side of the master signal line or the coupling signal line is arranged with a regulating device that can change distance between the master signal line and the coupling signal line, the regulating device is contacted with the master signal line or the coupling signal line through an insulating member, and the insulating member material is polycarbonate. The invention has stable product performance, simple manufacturing process, as well as low manufacturing cost.

Description

technical field [0001] The invention relates to a passive device used in a microwave communication device, in particular to a microwave coupler. Background technique [0002] Ordinary couplers for microwave communication generally include a housing with an inner cavity, in which the main signal line and the coupling signal line are arranged, and an adjustment component is also provided, through which the main signal line and the coupling signal are adjusted. The spacing between the lines is adjusted to achieve the purpose of adjusting the coupling energy. An insulating piece is arranged between the adjusting part and the main signal line or the coupling signal line, and the insulating piece currently used in this structure is generally made of polytetrafluoroethylene. The material is soft, easily deformed, and greatly affected by the ambient temperature, thus affecting the stability of the microwave coupler operation. In addition, when the insulating part of this material ...
