Wrapped Codirectional Directional Coupler

Abstract

Disclosed is a coated forward directional coupler, comprising a metal shielding outer box and a directional coupler structure arranged in the metal shielding outer box. The directional coupler structure comprises a first coupler structure and a second coupler structure; one end surface of the first coupler structure is provided with a spacer bar, and the other end surface is provided with a feeder panel; one end of the feeder panel is electrically connected to the other end surface of the first coupler structure, and the other end of the feeder panel extends towards the direction of the spacer bar to form a coupler bar. The coated forward directional coupler is easier to be assembled during assembly, is very easy to be maintained and overhauled, and is also very easy to be adjusted due to the reasonable setting of a coupler part where the coupling degree and other electrical performance parameters can be easily adjusted by just rotating coupling wings at two sides. The coated forward directional coupler is superior to other directional couplers in seismic tests. According to the present invention, by virtue of the design of the U-shaped coupler bar, the coupler bar, the spacer bar, and a signal input bar are arranged in the same direction, thereby bringing more convenience in use and wiring.

Description

technical field [0001] The invention relates to a cladding type co-directional directional coupler. Background technique [0002] The directional coupler is a general microwave or millimeter wave component, which is used to distribute the input signal according to a certain power ratio; the directional coupler is widely used in various microwave circuits, and can be used as a power divider for Signal isolation, separation and mixing, etc. When a transmission signal is input into the main line from one end of the main line, part of the power is output from the other end of the main line. Due to the mutual coupling between the main line and the secondary line, the power transmitted in the main line can be partially coupled to the secondary line , and make the power propagation in the sub-line directional, that is, one end of the sub-line, that is, the coupling end, has power output, and the other end, that is, the isolation end, has no signal output, so that the input signal ...

AI Technical Summary

Problems solved by technology

[0003] Existing directional couplers, except stripline directional couplers, most of the structures of other directional couplers are closed, which is difficult to manufacture, and because most of the directional couplers are molded at one time, it is difficult to adjust, and the assembly poor rear stability
