Abstract

Disclosed are a circulator, an isolator and a circuit assembly in an embodiment of the invention. The circulator comprises a shell and an internal component, the shell comprising a ground pin for connecting a printed circuit board. By employing the circulator of the present embodiment, the quality of port signals can be improved, thus the stability of the whole communication system can be improved. The isolator and circuit assembly are also disclosed in the embodiment of the present invention.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a circulator, an isolator and a circuit assembly. Background technique [0002] A circulator or isolator is a multi-port device in which the transmission of electromagnetic waves circulates in one direction, and the opposite direction is isolated, or counter-rotated. [0003] The principle of a circulator is that a magnetic field biases the anisotropic properties of the ferrite material. The ferrite material is used as the medium, the conduction band structure is placed on the top, and a constant magnetic field is applied, so that the circulator has a toroidal characteristic. If you change the direction of the bias magnetic field, the direction of the loop changes. In the base station system, devices with unidirectional loop characteristics should be used. For example, a circulator is often used at the output port of the base station power a...
