Embodiment Construction

[0012] The present invention relates to a stackable non-contact broadband high-power hinge, the specific implementation of which is as follows (see figure 1 , figure 2 with image 3 ):

[0013] 1. Design the coaxial cable 7. According to the number of channels of the stacked rotary hinge, the inner diameter inD of the coaxial line is designed to ensure that the multi-channel signal input cable 11 passes through, and the characteristic impedance Z of the coaxial line 0 40-60Ω, determine the outer diameter otD of the coaxial line, and at the same time, in order to prevent the occurrence of high-order modes, the minimum operating wavelength in the operating frequency range must satisfy λ min >π(inD+otD) / 2;

[0014] 2. Design of input signal excitation and output signal coupling. First design the inner and outer diameters of the stub radial line 5(6) with Height d4, then design the gap d1 between the input (output) voltage probe 1 (2) and the outer conductor 12 of the co...

Abstract

The invention relates to an accumulated non-contact broadband high-power rotating hinge and an achievement method thereof and belongs to the technical field of radar countermeasure antennas and microwaves. The accumulated non-contact broadband high-power rotating hinge and the achievement method are mainly used for solving the problem of broadband high-power input signal stimulus and output signal coupling of an accumulated multi-channel non-contact rotating hinge. According to the accumulated non-contact broadband high-power rotating hinge, short sections of radial lines are arranged at an input end and an output end of the accumulated non-contact broadband high-power rotating hinge respectively to support voltage probes to achieve input signal stimulus and output signal coupling; multi-stage impedance gradient matching sections are arranged in front of an input voltage probe and an output voltage probe respectively; gaps are formed between the input and output voltage probe and a coaxial line outer conductor; the multi-stage impedance gradient matching sections are connected with the coaxial line outer conductor; a radial choking device is arranged between a rotating portion and a relatively stationary portion of the coaxial line outer conductor; and a coaxial line inner conductor is utilized as an integral structure to penetrate multi-channel input signal cables of the accumulated non-contact broadband high-power rotating hinge.

Description

technical field [0001] The invention is a stackable non-contact broadband high-power rotary hinge. The invention is mainly used to solve the problem of a stackable multi-channel non-contact rotary hinge broadband high-power input signal excitation and output signal coupling. The invention belongs to the field of radar countermeasure antenna and microwave technology. Background technique [0002] The multi-band multi-channel microwave signal transmission system is an important part of radar and countermeasure equipment. Radar equipment generally uses antenna rotation scanning to obtain information in 360-degree omni-directional airspace, and multi-channel rotating hinges must be used between antennas and fixed transceivers to realize multi-band and multi-channel microwave signal transmission. [0003] The contact sliding friction structure is adopted between the rotating part of the broadband rotary hinge and the relatively static part, but the rotary hinge designed by this...
