Abstract:
Improvement in linearity is achieved at low costs in a power amplifier module employing an envelope tracking system. The power amplifier module includes a first power amplifier circuit that amplifies a radio frequency signal and that outputs a first amplified signal, a second power amplifier circuit that amplifies the first amplified signal on the basis of a source voltage varying depending on amplitude of the radio frequency signal and that outputs a second amplified signal, and a matching circuit that includes first and second capacitors connected in series between the first and second power amplifier circuit and an inductor connected between a node between the first and second capacitors and a ground and that decreases a gain of the first power amplifier circuit as the source voltage of the second power amplifier circuit increases.

Claim (Index 1):
A power amplifier module comprising:\n a first power amplifier circuit configured to amplify a radio frequency signal and output a first amplified signal; a second power amplifier circuit configured to amplify the first amplified signal on the basis of a source voltage varying depending on amplitude of the radio frequency signal and output a second amplified signal; a first power supply terminal configured to be used to supply the source voltage to the first power amplifier circuit; a second power supply terminal configured to be used to supply the source voltage to the second power amplifier circuit; a second inductor; and a ferrite bead serially connected to the second inductor, wherein the source voltage is supplied from the first power supply terminal to the first power amplifier circuit through the second inductor and the ferrite bead, and wherein the source voltage is supplied from the second power supply terminal to the second power amplifier circuit without passing through any ferrite bead.
