Abstract: 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.

Abstract: A module substrate has first and second main surfaces that on opposite sides of the module substrate, a resin member that covers the second main surface, and a plurality of post electrodes that are spaced apart from each other on the second main surface and penetrate through the resin member from the second main surface. The plurality of post electrodes includes a first post electrode and a first recess recessed toward the second main surface and formed in at least part of a region of the surface of the resin member that surrounds a leading end part of the first post electrode.
