Radio-frequency circuit, radio-frequency module, and communication device

A radio-frequency circuit comprising:

• a first filter having a first pass band;
• a second filter having a second pass band that is the same as the first pass band;
• an amplifier having an input terminal and an output terminal and connected to the first filter and the second filter;
• a first switch;
• a second switch;
• a first balun having a first coil and a second coil;
• and
• a second balun having a third coil and a fourth coil,
• wherein in the first balun,
• a first end of the first coil is connected to a terminal of the input terminal and the output terminal of the amplifier that is connected to the first filter and the second filter,
• a second end of the first coil is connected to a ground,
• a first end of the second coil is connected to the first switch,
• a second end of the second coil is connected to the second switch,
• in the second balun,
• a first end of the third coil is connected to the first end of the second coil via the first filter and the first switch,
• a second end of the third coil is connected to the second end of the second coil via the second filter and the second switch,
• a first end of the fourth coil is connected to a signal path, and
• a second end of the fourth coil is connected to the ground.
