Abstract

The invention discloses a space-borne dual-band four-channel rotary joint, comprising a first single-waveguide rotor, a first double-waveguide stator, a double-waveguide rotor, a second double-waveguide stator, a second single-waveguide rotor; a first single-waveguide rotor, a double-waveguide The waveguide rotor and the second single-waveguide rotor are rotors, the first double-waveguide stator and the second double-waveguide stator are stators; the first double-waveguide stator is arranged between the first single-waveguide rotor and the double-waveguide rotor and connected by bearing support, and the second The two double-waveguide stators are arranged between the second single-waveguide rotor and the double-waveguide rotor and are supported and connected by bearings. The rotor and the stator can rotate relatively; the dual-band four-channel rotary joint of the present invention has two high-frequency four-channels of Ka and K frequency bands The rotary joint has the advantages of high operating frequency and a large number of channels. The concentric stacking structure makes each channel independent of each other, ensuring high isolation requirements between channels.

Description

Technical field [0001] The present invention relates to the field of on-based microwave feeder, and more particularly to a star-loaded dual-band four-channel rotary joint. Background technique [0002] The rotation joint is a radio frequency signal in the continuous rotary antenna system to maintain a continuous device, which is a key component in various microwave systems. When the multiplex signal is transmitted between the antenna and the transmitter and the receiver, in order to achieve multi-function and structural optimization of the microwave system, multiple channel rotation with a larger microwave signal channel, and each channel has different frequency bands. joint. [0003] Multi-channel rotary joint is accumulated by a plurality of rotational joints, i.e., the routing joint is falling on the upper side of the other path; or is nestled by a plurality of rotational joints, that is, rotate all the way The joint sleeve is outside the other side of the rotation joint; it c...
