Abstract

The invention relates to a high-power rotary hinge based on waveguide distributors and an implementation method of the high-power rotary hinge and mainly aims to inhibit the excitation of a TE11 high-order mode. The high-power rotary hinge has the advantages that in order to increase the power capacity of the high-power rotary hinge, the size design of the inner and outer diameters of a coaxial line allows a TEM dominant mode and the TE11 high-order mode to be able to be transmitted in the coaxial line; the waveguide distributors are designed at the input end and the output end of the rotary hinge, a multi-order impedance conversion section and matching-regulating partition are designed to divide a transmission signal into two equal-amplitude in-phase signals, a rectangular waveguide TE10 mode is converted into the coaxial line TEM dominant line by designing a metal-ring-structure excitation device, the excitation of the TE11 high-order mode is inhibited, a choke device is designed between a conductor in the coaxial line and a metal ring structure, and a large through hole can be formed in the conductor in the coaxial line so as to penetrate a multichannel rotary hinge signal transmission cable to facilitate multichannel accumulation.

Description

technical field [0001] The invention relates to a high-power rotary hinge based on a waveguide divider and its realization method, which are suitable for electronic equipment such as modern radars. The invention belongs to the field of radar antenna and microwave technology. Background technique [0002] Radar equipment generally adopts the antenna rotation scanning method to obtain information in a full range of 360° airspace. A rotating hinge must be used between the antenna and the signal transceiver device to realize high-power microwave signal transmission. High-power microwave signal transmission systems are important for radar and other equipment. component. [0003] Rotary hinges generally use the input and output waveguides of the rotary hinge to directly convert the modes between the coaxial lines of the rotary hinge to realize signal transmission, and the inner and outer diameters of the coaxial lines are Φ 1 and Φ 2 , in order to effectively reduce high-order ...
