Abstract
The present invention provides a high-frequency switch including: a first switching element connected between a first input/output terminal and a second input/output terminal; a second switching element connected between the second input/output terminal and the first switching element; a high-frequency line provided between the first input/output terminal, the first switching element, and a third input/output terminal; and a third switching element connected between the third input/output terminal, the high-frequency line, and a ground. By connecting the first switching element, the second switching element, the high-frequency line, and the third switching element, because there exists no FET through which a large current flows when a state between the first input/output terminal and the third input/output terminal is set to a transmission state which requires high power handling capability, there is no need to use an FET having a large gate width, which is effective in reducing a loss of the switch.
