Abstract
This disclosure provides systems, methods and apparatuses for characterizing and operating a power amplifier. Before being placed into operation, output phase and output gain characteristics of the power amplifier may be determined over various operating conditions including varying two independent control signals and a supply voltage. The output phase and output gain characteristics may be stored for later retrieval. The power amplifier may be operated by determining a control signal profile for the two independent control signals based on operating conditions and radio-frequency (RF) envelope information associated with an input signal received by the power amplifier. The independent control signals may be generated in accordance with the control signal profile.
