Abstract
A switch module includes a multilayer substrate including an antenna terminal, a ground terminal, and a high-frequency-side transmission signal terminal, as external connection terminals. A common-port-side circuit, a switch circuit, and a switching-port-side circuit are provided between the antenna terminal and the high-frequency-side transmission signal terminal. A first wiring portion connects a second inductor that defines a portion of the switching-port-side circuit to the high-frequency-side transmission signal terminal. When the multilayer substrate is viewed in plan, a first inductor, the second inductor, and via electrodes connected to the ground terminal are arranged between the first wiring portion, and second and third wiring portions and a capacitor which are connected to the antenna terminal.
