Abstract
A switch circuit with a unit capable of improving a margin voltage without using a negative bias generation circuit is provided. A switch comprising an N-type MOSFET is used for a switch passing a signal to an antenna and a switch comprising a P-type MOSFET is used for a shunt switch grounding a signal. A common control signal is input to the gate terminal of the MOSFET constituting each switch. The inverted signal of this control signal is coupled to a ground terminal of the switch, and thus the potential of the gate terminal of each MOSFET can be set to the ground voltage.
