Abstract:
1. A switch circuit comprising: first, second, and third input-output terminals; a first switching element connected between the first input-output terminal and the second input-output terminal; a second switching element connected between the third input-output terminal and a grounding point; a third switching element connected between the first input-output terminal and the third input-output terminal; a fourth switching element connected between the second input-output terminal and the grounding point; a first control voltage applying terminal connected to control terminals of the first and second switching elements; a second control voltage applying terminal connected to control terminals of the third and fourth switching elements; a first resistor connected between the control terminal of the first switching element and the first control voltage applying terminal; a second resistor connected between the control terminal of the second switching element and the first control voltage applying terminal; a first diode and a first inductor connected in series, wherein the series-connected first diode and first inductor are connected in parallel with the first resistor, and a second diode and a second inductor connected in series, wherein
