Four-port circulator

Abstract

A four-port circulator, includes: a first port, a second port, a third port, a fourth port, a ferrite, and a microwave transmission chamber; wherein the first port, the second port, the third port, and the fourth port are symmetrically distributed around the microwave transmission chamber, and connected to the microwave transmission chamber; wherein the ferrite is horizontally provided on an upper surface or a lower surface of a center position of the microwave transmission chamber. The four-port circulator of the present invention aims to reduce the volume and cost of the four-port waveguide circulator.
