A first passive component includes one unbalanced line having one unbalance input terminal, one balanced line installed opposite to the unbalanced line and having two balanced output terminals (first balanced output terminal and second balanced output terminal), and a capacitor formed between the balanced line and a fixed potential (e.g. the ground potential). Furthermore, the relation d&#x3e;dis satisfied, where dis the physical length of the unbalanced line and dis the physical length of the balanced line.

Passive component

A passive component is provided with a filter section employing a nonequilibrium input/output system, which has an input side resonator connected to a nonequilibrium input terminal, and an output side resonator coupled with the input side resonator; and a converting section having two double line coupled lines. An output stage of the filter section is connected with an input stage of the converting section through a first capacitor, and an input stage of the filter section is connected with the input stage of the converting section through a second capacitor. Namely, the second capacitor functions as a jump capacitor. The position of an attenuation pole is permitted to be adjusted by a second capacitor in a region low in frequency characteristics.
