Nonreciprocal circuit element with reduced insertion loss and excellent manufacturability

Abstract

A nonreciprocal circuit element with reduced insertion loss and excellent manufacturability is provided. The nonreciprocal circuit element includes first, second, and third central conductors 5, 6, and 7 located on a ferrite member 4 on different planes in a vertical direction with dielectric bodies sandwiched therebetween so that parts thereof cross each other in the vertical direction, a first yoke 1 arranged so as to cover a magnet 2, a second yoke 3 that constitutes a magnetic closed circuit together with the first yoke 1, and an insulating base 8 made of a molded synthetic resin for positioning the ferrite member 4. A plurality of input and output terminals 9 and 10 made of a material having a smaller electric resistance than that of the second yoke 3 is mounted in the insulating base 8. As a result, it is possible to obtain a nonreciprocal circuit element with reduced insertion loss compared to the conventional nonreciprocal circuit design.
