Radio-frequency module and communication apparatus

A radio-frequency module comprising:

• a transmission-reception terminal, a first reception terminal, a second reception terminal, and a transmission terminal;
• a first transmission path having a first end connected to the transmission terminal;
• a first reception path having a first end connected to the first reception terminal;
• a second reception path having a first end connected to the second reception terminal;
• a first switch that has a first common terminal, a first selection terminal, and a second selection terminal, and that is configured to selectively connect the first common terminal to the first selection terminal or to the second selection terminal;
• and
• a second switch that has a second common terminal, a third selection terminal, and a fourth selection terminal, and that is configured to selectively connect the second common terminal to the third selection terminal or to the fourth selection terminal,
• wherein the first common terminal is connected to the transmission-reception terminal,
• wherein the first selection terminal is connected to the second common terminal,
• wherein the second selection terminal is connected to a second end of the first transmission path,
• wherein the third selection terminal is connected to a second end of the first reception path,
• wherein the fourth selection terminal is connected to a second end of the second reception path,
• wherein the second switch is connected to the first and second reception paths, and is not connected to the transmission path,
• wherein a transmission signal in a first communication band input through the transmission terminal is transmitted on the first transmission path,
• wherein a reception signal in a second communication band input through the transmission-reception terminal is transmitted on the first reception path,
• wherein a reception signal in a third communication band input through the transmission-reception terminal is transmitted on the second reception path,
• wherein the second switch further has a fourth common terminal and an eighth selection terminal,
• wherein the radio-frequency module further comprises:
• a third reception path connected to the eighth selection terminal and on which a reception signal in the fourth communication band input through the transmission-reception terminal is transmitted;
• and
• a second filter that has an input terminal connected to the second selection terminal, that has an output terminal connected to the fourth common terminal, and that has an attenuation band comprising a transmission band of the first communication band,
• wherein a path connecting the first selection terminal to the second common terminal is a first bypass path on which no filter is arranged, and
• wherein the transmission of the transmission signal in the first communication band on the first transmission path is performed concurrently with the transmission of the reception signal in the fourth communication band on the third reception path.
