HIGH-FREQUENCY CIRCUIT ELEMENT

摘要

A high-frequency circuit element that realizes a high degree of input-output coupling without causing an increase in loss and irregularity in impedance. A resonator made of a conductor film is formed on a substrate made of a dielectric monocrystal or the like. An input-output line made of a conductor film having a uniform line width is formed on the same surface of the substrate as the surface on which the resonator is formed. A part of the side edge of the input-output line is located along a coupling part on the peripheral part of the resonator and spaced from the resonator by a gap part.
