The Linearization ofTwo Multichannel Amplifiers Connected inCascadeby UsingtheSecondHarmonics andFourth-Order NonlinearSignals

Thelinearization oftwoamplifiers connected in cascade hasbeenperformed inthis paperbytheinjection ofthe fundamental signals' second harmonics (IM2signals) atthe inputs ofthefirst amplifier andIM2signals together withthe fourth-order nonlinear signals intothesecondamplifier in cascade.
