Original Abstract Submitted

A radio frequency module includes a carrier amplifier and a peak amplifier. A 90° hybrid circuit is connected to an input end of the carrier amplifier and an input end of the peak amplifier. A coupler is connected to an output end of the carrier amplifier and an output end of the peak amplifier. A control circuit varies a threshold value of a bias voltage of the peak amplifier based on a radio frequency signal input to the 90° hybrid circuit or the carrier amplifier, and a signal indicating a drive level of the carrier amplifier. The carrier amplifier and the peak amplifier are included in an integrated circuit, the control circuit is included in another integrated circuit, and the other integrated circuit is disposed adjacent to the integrated circuit on a carrier amplifier side out of the carrier amplifier and the peak amplifier.
