Abstract
A distortion module includes a first module, at least one module and a correction module. The first module is configured to (i) receive radio frequency signals from radio frequency sensors of a power amplifier, and (ii) generate a distortion signal indicating distortion values for the radio frequency signals. The radio frequency signals are indicative of radio frequency power out of the power amplifier and received by a transmission line. At least one module is configured to estimate a phase of the distortion signal. The phase of the distortion signal is indicative of a phase of the transmission line. The correction module is configured to generate a distortion correction signal based on the phase to correct at least one of the distortion values of the radio frequency signals.
