Abstract
An in-situ delay measurement is performed for an envelope-tracking power amplifier of an RF input signal. Because the delay measurement is in-situ, the delay measurement avoids the necessity to down convert and digitize a version of an RF output signal from the envelope-tracking power amplifier.
