Rth (0 Hz) and Zth (f1 − f2 ) are the thermal resistor value at zero frequency and the thermal impedance at frequency ( f1 − f2 ); and pdissipated (0 Hz) is the DC component of the power dissipation. 21 includes two terms. 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.

Published 2015 by John Wiley & Sons, Ltd. 1 Generic block diagram for behavioral model performance assessment comparing the measured baseband discrete time output signal samples (ymeas (n)) with those estimated by the model (yest (n)). The similarity between these two signals can be evaluated using various metrics that are calculated either in the time domain or in the frequency domain. 1 includes a feedback path from the performance assessment block back to the model.
