Abstract
A power amplification module includes a carrier amplifier circuit; a carrier bias circuit that supplies a bias to the carrier amplifier circuit; a peak amplifier circuit; and a peak bias circuit that includes a first transistor having a collector or a drain connected to a reference potential and that supplies a bias to the peak amplifier circuit from an emitter or a source of the first transistor. The peak bias circuit is electrically connected to a current output circuit that outputs a predetermined current from the emitter or the source of the first transistor.
