Abstract
An impedance matching switch circuit module includes a first switch device connected to first and second high-frequency input/output terminals, a second switch device connected between the first high-frequency input/output terminal and a first matching terminal, and a third switch device connected between the second high-frequency input/output terminal and a second matching terminal. Impedance matching elements having appropriately set element values (inductances or capacitances) are connected to the first and second high-frequency input/output terminals and the first and second matching terminals, and on/off control is performed for the first, second, and third switch devices.
