Abstract
A power amplifier includes a power amplifier core in which a transmit signal having an amplitude-modulated (AM) component and a phase-modulated (PM) component is passed and amplified, the power amplifier comprising a forward path, and an additional amplification device configured to generate an output that is proportional to an output of the power amplifier core, such that the output of the additional amplification device indirectly controls the output of the power amplifier core.
