Abstract
Disclosed is a semiconductor switch which has: a first resonance circuit which is composed so that a variable capacitance element and an inductor are in series connected and a series circuit composed of an inductor and a capacitor are in parallel connected to the variable capacitance element and the inductor, the first resonance circuit having one end connected to an input terminal and the other end connected to a first output terminal; a second resonance circuit which is composed like the first resonance circuit and is grounded to the first output terminal; a third resonance circuit which is composed like the first resonance circuit and is connected to the input terminal in parallel with the first resonance circuit, the third resonance circuit having a second output terminal on the reverse side of the input terminal; and a fourth resonance circuit which is composed like the first resonance circuit and is grounded to the second output terminal.
