Characteristics of this nonlinear system were also presented in detail along with the metrics to quantify the amount of nonlinear distortion. In this chapter, dynamic nonlinear power amplifiers will be introduced.
The first term is related to the DC dissipation and is frequency independent. 7 Simplified transistor thermal modeling is function of the envelope dissipation and is frequency dependent, which means that any change in the transistor characteristics due to the temperature variation results in frequency dependent effects or memory effects. Much research work has investigated the temperature variation in the power transistor junction for different types of signals in order to model it and understand its effect on the generation of thermal memory effects.
