摘要： PROBLEM TO BE SOLVED: To solve the problem that in a conventional high-frequency switch, passage loss in small power input increases as a gate width of an FET, which is a switching element, is enlarged for enlarging power resistance.
SOLUTION: A first switching element is connected between a first input/output terminal and a second input/output terminal, a second switching element is connected between the second input/output terminal-to-the first switching element and a ground, a high-frequency line is connected between the first input/output terminal-to-the first switching element and a third input/output terminal, and a third switching element is connected between the third input/output terminal-to-the high-frequency line and the ground. Consequently, when the first input/output terminal-to-the third input/output terminal is made a passage state which requires high power durability, an FET wherein a large current flows does not exist, thus eliminating the need for an FET of a large gate width. It is effective for reduction in loss of a switch.
