Magnetic shield assembly of circulator

Abstract

The invention discloses a magnetic shield assembly of a circulator. The magnetic shield assembly comprises a cavity (1) and one or more shield plates (2), wherein the upper part, the lower part and the periphery of the cavity (1) are respectively provided with at least one shield plate (2) to form a closed magnetic circuit. According to the magnetic shield assembly of the circulator provided by the invention, a low-magnetic-resistance channel is provided, the advantages of increasing the magnetic circuit efficiency of the circulator, reducing magnetic leakage and reducing the influence of an external magnetic field to the electric performance of the circulator are achieved, magnetic-sensitive components around the circulator are protected from the influence of the magnetic field of the circulator, the energy of a permanent magnet is concentrated inside the circulator as much as possible, and thus, the maximal energy utilization rate is achieved.

Description

technical field [0001] The invention relates to a magnetic shield assembly of a circulator. Background technique [0002] The circulator is a multi-port device that transmits the incident wave entering any port to the next port in sequence according to the direction determined by the static bias magnetic field. The existing circulators have large magnetic leakage, low magnetic circuit efficiency, and the external magnetic field has a great influence on the electrical performance of the circulator. The magnetically sensitive components around the circulator are easily affected by the magnetic field of the circulator, and the energy of the permanent magnet is only A small part is concentrated in the circulator, and the energy utilization rate is low. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, provide a magnetic shield assembly for a circulator, provide a low reluctance channel, improve the magnet...
