The first filter and the second filter are connected to the first selection terminal. The third filter and the fourth filter are connected to the second selection terminal. The first filter and the third filter are band pass filters. The second filter is a band elimination filter. A pass band of the first filter and a rejection band of the second filter overlap each other. The pass band of the first filter and a pass band of the third filter overlap each other.
