摘要： 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.

摘要： A single pole single throw switch for controlling propagation of a high frequency signal between an input terminal (11a) and an output terminal (11b). First FET switches (14a, 14b) in which drains and sources of FETs (12a, 12b) are connected in parallel with inductors (13a, 13b) are connected in parallel. Each FET (12a, 12b) is switched between on state and off state by a voltage being applied to the gate thereof. At the frequency of the high frequency signal, each inductor (13a, 13b) connected with off capacitor of each FET (12a, 12b) resonates in parallel.
