ABSTRACT:
A balanced high-frequency device includes a balanced element; at least one balanced terminal connected to the balanced element; a phase circuit having at least first, second, and third impedance elements, and electrically connected between the balanced element and the balanced terminal. The first impedance element and the second impedance element are connected between the balanced terminals in series, the connection point between the first impedance element and the second impedance element is grounded through the third impedance element, a series resonant circuit is formed by the first impedance element and the third impedance element. A series resonant circuit is formed by the second impedance element and the third impedance element, and an impedance to a differential signal component in the passing band of the balanced elements of the first and second impedance elements is set so as to increase to the ground plane.
