Embodiment 1

[0043] A high-performance full-band horizontal exit waveguide coaxial converter, such as figure 1 and figure 2 As shown, it includes a socket 1 , a supporting medium 3 , a ferrule 2 , a spacer 4 and a waveguide cavity 5 connected in sequence.

[0044] The support medium 3 falls into the stepped hole opposite the socket 1 and the gasket 4. The cross section of the support medium 3 is circular, and there are 6 through holes 31 on the periphery of the central hole structure. The opening diameter of the through holes is smaller than the diameter of the medium support and The difference between the diameters of the center hole should be as large as possible within the size range that meets the processing requirements; an air cavity is formed between the small end of the step hole of the socket 1 and the gasket 4 and the ferrule 2, and the diameter of the small end is 2.92. The diameter of the air section of the K-type joint is the same. A booster groove 41 is designed on the end ...

Abstract

The invention provides a high-performance full-band horizontal outlet waveguide coaxial converter. The high-performance full-band horizontal outlet waveguide coaxial converter comprises a socket (1), a supporting medium (3), an insertion core (2), a gasket (4) and a waveguide cavity (5) which are connected in sequence, the joint form and size are accurately designed, the port impedance is matched, and the wave-same conversion electrical performance is optimized; the shape and the size of the insertion core are adjusted, steps are designed on the insertion core, the medium supporting position is fixed through cooperation of the insertion core and the cavity, the installation mode between the coaxial interface and the waveguide cavity is adjusted, and the reliability and the electrical performance consistency of the waveguide-coaxial conversion structure are improved. A gasket is adopted to replace a bushing form in a traditional design and is used for fixing a medium supporting position, impedance matching of a coaxial end is achieved by designing the size of a gasket opening, the purpose of restraining a high-order mode is achieved, and wave-same conversion full-band design is achieved.

Description

technical field [0001] The invention belongs to the technical field of microwave wave co-conversion, in particular to a high-performance full-band horizontal exit waveguide coaxial converter. Background technique [0002] The waveguide-to-coaxial converter (hereinafter referred to as the wave-to-coaxial converter) is used to realize the conversion from the waveguide interface to the coaxial interface. It is widely used in passive microwave products and is an indispensable part of various systems of spacecraft. It is also widely used in In the process of testing the system and debugging the product. With the increasing demand for the use of spacecraft, the bandwidth requirements and RF performance requirements for the wave-to-wave conversion are also getting higher and higher. Limited by the performance of the RF connector, the wave-to-wave conversion above the Ka frequency band mostly relies on imports. In order to replace the imported products , Realized the localization o...
