Abstract

Abstract 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.
