Radio-frequency circuit

A radio-frequency circuit comprising:

• a first power amplifier that supports a first power class, the first power class allowing for maximum output power higher than power class 3;
• a second power amplifier;
• a first filter that has a pass band including a first band and that is connected between the first power amplifier and an antenna connecting terminal;
• a second filter that has a pass band including a second band and that is connected between the second power amplifier and the antenna connecting terminal, the radio-frequency circuit being able to perform simultaneous communication of the first band and the second band;
• and
• an attenuation circuit and a switch that are connected in series with each other between a ground and a transmit path, the transmit path connecting the second power amplifier and the antenna connecting terminal, wherein
• the attenuation circuit has an attenuation band including at least part of the first band and includes an inductor which is connected between the transmit path and the ground,
• the switch has a first terminal connected to the attenuation circuit and a second terminal connected to the transmit path or the ground, and
• the switch connects the first terminal to the second terminal based on the radio-frequency circuit being in a state to perform simultaneous communication of the first band and the second band, and the switch does not connect the first terminal to the second terminal based on the radio-frequency circuit not being in the state to perform simultaneous communication of the first band and the second band.
