A power amplifier is capable of operating in a first power mode and a second power mode with a gain lower than a gain of the first power mode. The power amplifier is connected to a first common terminal of the first switch. Two or more filters are connected to two or more first selection terminals other than at least one first selection terminal among three or more first selection terminals of the first switch. The at least one first selection terminal of the first switch and at least one second selection terminal of a second switch are connected. The first switch is capable of switching between a first path passing through at least one of the two or more filters and a second path not passing through any of the two or more filters but passing through the at least one first selection terminal.
