Abstract
The present disclosure relates to an envelope tracking system that is configured to improve the performance of radio frequency power amplifier circuitry by compensating for errors that become more significant as modulation bandwidth increases. These errors include power amplifier collector-base capacitance, time delay between power amplifier stages, and interconnect distance between the baseband modulation source and the power amplifier collector.
