Abstract:
1. An unbalanced-balanced conversion circuit element comprising: an unbalanced terminal that inputs/outputs an unbalanced signal; a pair of balanced terminals including a first balanced terminal and a second balanced terminal that input/output a balanced signal; a first inductor connected in series between the unbalanced terminal and the first balanced terminal; a first capacitor connected in series between the unbalanced terminal and the second balanced terminal; an impedance adjustment element including an inductor or a capacitor that is connected between the first balanced terminal side of the first inductor and the second balanced terminal side of the first capacitor; and a laminate in which a plurality of dielectric layers are laminated; wherein the first inductor, the first capacitor, and the impedance adjustment element are defined by electrode patterns that are located on the plurality of dielectric layers of the laminate; and the first inductor and the impedance adjustment element are disposed between the first capacitor and a mounting surface of the laminate.
