A switch module includes a filter that allows a signal in a first frequency range to pass therethrough, a filter that allows a signal in a second frequency range to pass therethrough, an impedance load circuit, and an antenna switch including a common terminal connected to an antenna element, a first selection terminal connected to the filter, a second selection terminal connected to the filter, and a third selection terminal connected to the impedance load circuit. When only one frequency range is selected from among the first and second frequency ranges, the antenna switch connects the common terminal to only one of the first and second selection terminals and connects the common terminal to the third selection terminal.
