Abstract
An average power tracking (APT) power amplifier apparatus is provided. In a non-limiting example, the APT power amplifier apparatus includes multiple sets of power amplifier circuits configured to amplify a radio frequency (RF) signal(s) for transmission in different polarizations (e.g., vertical and horizontal). In examples disclosed herein, the APT power amplifier apparatus can be configured to employ a single power management integrated circuit (PMIC) to provide an APT voltage to all of the power amplifier circuits for amplifying the RF signal(s). By employing a single PMIC in the APT power amplifier apparatus, it is possible to reduce footprint, power consumption, and costs of the APT power amplifier apparatus.
