Abstract
A non-reciprocal circuit device comprising a first inductance element connected between a first input/output port and a second input/output port, a second inductance element connected between the second input/output port and the ground, a first capacitance element connected between the first input/output port and the second input/output port for constituting a parallel resonance circuit with the first inductance element, a second capacitance element connected between the second input/output port and the ground for constituting a parallel resonance circuit with the second inductance element, and a resistance element connected between the first input/output port and the second input/output port, the first and/or second capacitance elements being constituted by parallel-connecting capacitors formed by electrode patterns in a multilayer substrate comprising dielectric sheets and the electrode patterns to chip capacitors mounted onto the multilayer substrate.
