Abstract

Disclosed is a switch circuit comprising one common input/output terminal, two switching input/output terminals, series field effect transistors respectively inserted between the common input/output terminal and the two switching input/output terminals, shunt field effect transistors respectively inserted between the two switching input/output terminals and the ground, and resistors respectively inserted between the ground and the common input/output terminal and between the ground and the two switching input/output terminals, the resistors having the resistance values smaller than that of the shunt field effect transistors at OFF state.
