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 adaptive predistortion and adaptive closed-loop control of the drain current of the power amplifier to achieve improved power amplifier performance.
