Multiplexer and communication apparatus

A multiplexer comprising:

• a common terminal;
• a first terminal;
• a second terminal;
• a third terminal;
• a first matching circuit having a first end connected to the common terminal;
• a first filter that has a first end connected to a second end of the first matching circuit and a second end connected to the first terminal and that has a first pass band;
• a second matching circuit having a first end connected to the common terminal;
• a second filter that has a first end connected to a second end of the second matching circuit and a second end connected to the second terminal and that has a second pass band a low pass end of which is higher than a high pass end of the first pass band;
• and
• a third filter that has a first end connected to the common terminal and a second end connected to the third terminal and that has a third pass band a low pass end of which is higher than a high pass end of the second pass band,
• wherein the first matching circuit includes a first inductor connected on a first signal path connecting the first end of the first matching circuit to the second end thereof, the first inductor is not connected between the first signal path and ground,
• wherein the second matching circuit includes a second inductor connected between a second signal path connecting the first end of the second matching circuit to the second end thereof and the ground, and
• wherein a width of the third pass band is wider than a width of the first pass band and a width of the second pass band,
• wherein the number of matching circuits between the filters and the common terminal is less than the number of filters, and
• wherein the first end of the first matching circuit and the first end of the second matching circuit are each directly connected to a node that is connected to the common terminal.
