Title:
RESONANCE FILTER CIRCUIT AND CIRCUIT DEVICE
Document Type and Number:
Japanese Patent JPH10107570
Kind Code:
A
Abstract:
To simplify the circuit configuration with a few number of components, to reduce a signal loss and distortion and to make the circuit suitable for a high frequency circuit.
The circuit is an LC parallel circuit that is inserted in a path tying an input terminal 15 and an output terminal 17 and consisting of parallel connection between an inductor 13 and a 1st capacitor, a 2nd capacitor 16 inserted in series with the LC parallel circuit and an SPST switch 14 that is inserted in series with the 1st capacitor 12 in the LC parallel circuit to switch the capacitor 12.
