    摘要: According to one embodiment, a semiconductor switch circuit includes a switch section, a decoder section, a DC-DC converter, a driver section, a first filter circuit, a first filter bypass circuit and a first bypass control circuit. The switch section includes an input-output terminal, radio frequency signal terminals, and semiconductor switch elements. The decoder section generates a switch control signal controlling a conduction and a non-conduction state of switch elements. The DC-DC converter generates a first potential. The driver section supplies the first and a second potential to a gate electrode of the switch elements. The first filter circuit is electrically connected between the DC-DC converter and the driver section and outputs the first potential to the driver section. The first filter bypass circuit is electrically connected with the first filter circuit. The first bypass control circuit supplies a first mode signal to the first filter bypass circuit.
