IRREVERSIBLE CIRCUIT ELEMENT

摘要

A non-reciprocal circuit element includes a plurality of inner conductors intersecting with keeping insulation with each other, a shield conductor connected in common to one ends of the inner conductors, and a capacitor connected between the shield conductor and an ground of the non-reciprocal circuit element, for adjusting only eigen values of in-phase excitation. Thus, smaller size, lighter weight and lower height can be attained and also temperature characteristics can be optionally adjusted without changing material used and without inviting increased insertion loss. <IMAGE>
