Abstract :
The linearization of two amplifiers connected in cascade has been performed in this paper by the injection of the fundamental signals´ second harmonics (IM2 signals) at the inputs of the first amplifier and IM2 signals together with the fourth-order nonlinear signals into the second amplifier in cascade.
