Abstract:
Various embodiments described herein provide systems and methods for improved performance for power amplifiers, particularly GaN power amplifiers. According to some embodiments, a power amplifier (e.g., GaN power amplifier) utilizes an adaptive closed-loop control of the drain current of the power amplifier to achieve improved performance for the power amplifier. Additionally, for some embodiments, use of the adaptive closed-loop control of the drain current of the power amplifier depends on the power region in which the power amplifier is operating (e.g., depends on the radio frequency power region).
