Nonreciprocal circuit element with input and output characteristic impedances matched

摘要

A nonreciprocal circuit element includes a magnetic plate, a common electrode on a first surface of the magnetic plate, and first, second, and third central conductors each including a pair of divisions. The three central conductors extend from the common electrode, are bent along the magnetic plate towards a second surface of the magnetic plate, and cross one another on the second surface of the magnetic plate at a predetermined angle relative to one another. The first and second central conductors are connected to input and output terminals. The nonreciprocal circuit element satisfies the relationship theta₁>theta₂, where theta₁ is the angle between the divisions of the first central conductor and theta₂ is the angle between the divisions of the second central conductor, when the first central conductor is farther away from the magnetic plate than the second central conductor.
