Abstract

PURPOSE:To improve the isolation characteristics, by connecting two capacitors in series connection with each other, in parallel with the diode and connecting the inductance between the connection points of two capacitors and ground. CONSTITUTION:When the diode 12 is off, the series LC resonance circuit consisting of the lambda connection with the capacitor offered by the diode 12 and a pair of capacitors 13, 14 and the inductance 15 is constituted. Further, when the diode 12 is ON, the series LC resonance circuit consisting of a pair of capacitors 13, 14 and inductance 15 is constituted. Thus, the resonance frequency can be made different by turning-on and -off of the diode 12.
