ENCLOSED SURFACE MOUNT CIRCULATOR

WIPO Patent Application WO/2019/095793

A1

Disclosed is an enclosed surface mount circulator, comprising a cavity, a magnetic circuit assembly and three PIN assemblies, wherein the cavity comprises a shielding plate and a triangular column; one end of the column is provided with a circular blind hole and three port grooves; the magnetic circuit assembly is provided inside the blind hole, and the three port grooves are arranged in uniform distribution around a central axis of the blind hole, with the port grooves being in communication with the blind hole; the bottom of the port groove is provided with a through hole in communication with the other end of the column; a part of the PIN assembly penetrates the through hole and is electrically connected to the magnetic circuit assembly; and the shielding plate is fixedly connected to the column and encloses the blind hole and the port grooves. With the completely-enclosed cavity structure, the problems of magnetic leakage and electromagnetic incompatibility of an ultrahigh frequency circulator are effectively solved. When in use, there is no need to additionally provide a metallic shield, thereby greatly reducing the usage cost for a user. A first ferrite is sleeved with a dielectric ring, facilitating an increase in the performance of the surface mount circulator. The enclosed surface mount circulator has a small volume, a simple structure, is easily assembled and is suitable for mass production.
