Abstract
According to one embodiment, a semiconductor switch includes a voltage generator, a voltage controller, a driver, and a switch unit. The voltage generator generates a negative first potential. The voltage controller controls the first potential according to a terminal switch signal input from an outside. The driver is input the terminal switch signal, and outputs at least one selected from the first potential and the second potential based on the terminal switch signal. The second potential is a power supply voltage or is higher than the power supply voltage. The switch unit is provided on an SOT substrate, switches a connection between an antenna terminal and any one of high frequency terminals based on the output of the driver.
