Abstract :
Tap delay lines are introduced into a power amplifier feedforward lineariser for two purposes: first, to align the delays of the combining branches for both loops. Secondly, to equalise the power amplifier, which reduces the power of the linear distortion signals going through the auxiliary amplifier
