COMPOSITE SUBSTRATE TYPE CIRCULATOR

摘要

A composite substrate type circulator comprising a conductive thin film formed on a ferrite disc (10) and a second dielectric material film (4) for constructing a circulator circuit, the conductive thin film being made of a three-layered laminate structure which is composed of a first conductive film (3) formed on the upper faces of the ferrite disc (10) and the second dielectric material film (4), a nonmagnetic conductive layer film (1) formed on the first conductive film (3), and a second conductive film (2) formed on said nonmagnetic conductive film (1).
