Abstract
In a distributed constant circuit, a first line is connected between a first node and a second node. The first node is grounded through a series connection between a first capacitor and a second line, and the second node is grounded through a series connection between a second capacitor and a third line. The parameters of the first, second and third lines and the first and second capacitors satisfy a predetermined relational expression such that characteristics equivalent to a &lgr;/4 line are obtained with respect to the frequency of a fundamental wave, and the second and third lines and the first and second capacitors respectively resonate with respect to an arbitrary frequency.
