Document Type and Number:
Japanese Patent JP6187593
Kind Code:
B2
Abstract:
A resonant circuit includes a resonator. An inductor is connected in parallel with the resonator. An inductor is connected in series with the parallel circuit formed of the resonator and the inductor. Further, a variable capacitor is connected in parallel with a series circuit formed of the inductor and the parallel circuit formed of the resonator and the inductor. The variable capacitor is connected in series with these circuits. As a result, a resonant circuit and a high-frequency filter supporting more communication signals are provided.
