Compensation for one or more effects of impedance mismatch between a power amplifier (PA) and at least one filter is discussed. One example system that compensates for impedance mismatch with at least one filter comprises a PA, a measurement component, and a feedback component. The PA is configured to receive PA stimuli comprising a supply voltage and a radio frequency (RF) signal to be amplified, wherein a PA output is configured to be coupled to the at least one filter. The measurement component is coupled to the PA and configured to measure an output signal from the PA, wherein the output signal comprises a forward signal associated with the PA and a reflected signal associated with the at least one filter. The feedback component is configured to receive the output signal and to adjust one or more of the PA stimuli based at least in part on the output signal.
