Embodiment Construction

[0010] See attached picture.

[0011] The coupling device of the present invention is suspended on the inner conductor 401 of the main coaxial line. The coupling device is composed of the following parts: the inner conductor 401 of the main coaxial line, the output inner conductor 402 of the coupling end, the ring-shaped tetrafluoroethylene 403, and the metal barrel-shaped cylinder 404. Implementation process: the inner conductor 401 of the main coaxial line is composed of multiple concentric cylinders with different diameters and different lengths, in order to ensure processing accuracy and provide processing convenience. As well as the ease of assembly during the assembly process, the inner conductor 401 of the main coaxial line can be divided into multiple sections, which are connected in the form of threads. In this implementation process, the coupling device in the cavity is divided into two parts. First, install the inner conductor of the main coaxial line into the out...

Abstract

The invention relates to a coaxial power coupler. The coaxial power coupler comprises a port connector, main coaxial line internal and external conductors, coupling output internal and external conductors and a coupling device, wherein the coupling device is suspended on the main coaxial line internal conductor; the coupling device comprises a metal barrel-shaped column and annular tetrafluoride; the metal barrel-shaped column is vertical to a main transmission line; the annular tetrafluoride is positioned above the metal barrel-shaped column and is used for fixing; and the coupling output internal conductor is tightly matched with an air column insulator and is connected with the bottom surface of the metal barrel-shaped column. The coaxial power coupler has the advantages of realizing fourfold or higher frequency intervals in bandwidth and realizing low standing-wave ratio and low intermodulation at an input port easily, along with low coupling fluctuation when the coupling degree is larger.

Description

technical field [0001] The invention relates to a power coupler used in microwave technology fields such as communication and radar. Background technique [0002] Coaxial power coupler is similar to non-isolated power divider, and can also be regarded as a kind of unequal two power divider. It is mainly used for microwave signal coupling or synthesizing power according to a specific ratio. It is one of the commonly used components in the field of microwave technology, and it mostly appears in a coaxial structure. Generally, a component for coupling output is added to the main transmission line, so as to allocate a specific power from the main transmission line and output it from another port. The relationship between input power and coupled output power is the degree of coupling. The coaxial power coupler is characterized by simple structure, high carrying power and low intermodulation. The typical structure of the coupling part of the coaxial power coupler with a coaxial ...
