Abstract

The invention discloses a C-band heavy-power circulator. The circumference of a cavity (1) is respectively provided with a magnetic circuit plate (2), a cover plate (6) is fastened on the cavity (1), the cavity (1) comprises an upper cavity and a lower cavity which are symmetric in structure, a joint of the upper cavity and the lower cavity is provided with a center conductor (4), the upper cavity and the lower cavity are internally provided with permanent magnets (3), grounding sheets (7) and ferrite rotary magnetic sheets (5) sequentially from outside to inside, the two ferrite rotary magnetic sheets (5) in the upper cavity and the lower cavity are externally clamped on two sides of the center conductor (4) respectively, and a center conductor transition section (8) is coated outside the center conductor (4) and is filled with one or more layers of media (9) inside. The invention solves the problems of arcing, breakdown and the like under a non-linear effect and a heavy power, is beneficial to batch production due to the adoption of a low-field design, and has the advantages of light appearance, convenience in installation, easiness in processing, high power capacity, wide working temperature range, good temperature performance, reduced cost and the like.

Description

technical field [0001] The invention relates to a C-band high-power circulator. Background technique [0002] The circulator is a multi-port device that transmits the incident wave entering any port to the next port according to the direction determined by the static bias magnetic field. There are many types of circulators, which are divided into junction circulators, Faraday rotator circulator, differential phase shift circulator, etc. Compared with other circulators, junction circulators can meet the requirements of small size and high power, and also have the advantages of small loss, wide frequency band, and relatively mature technology. Junction circulators are divided into centralized parameter type and distributed parameter type according to parameters. The lumped parameters are only applicable to the microwave low frequency band (P-band). Distributed parameter stripline circulators can meet the requirements of C-band. This type of circulator can be divided into hi...
