Multiplexer, radio frequency front-end circuit, and communication device

A multiplexer comprising:

• a first filter having a first pass band;
• a second filter having a second pass band, the second pass band being different than the first pass band;
• a third filter having a third pass band, the third pass band being different than any of the first pass band and the second pass band;
• a first connection point connected to a common terminal;
• a second connection point to which a first end of the first filter and a first end of the second filter are commonly connected;
• a first switch configured to selectively connect the first connection point to the second connection point;
• a reactance element having a first end that is connected to a signal path, the signal path connecting the second connection point and the first switch;
• a second switch configured to selectively connect a second end of the reactance element to the first connection point;
• and
• a third switch configured to selectively connect a first end of the third filter to the first connection point,
• wherein the first pass band and the second pass band are adjacent to each other among the first pass band, the second pass band, and the third pass band.
