Microwave transistors noise modeling by using variable noise wave temperatures

In this paper we proposed a new noise modeling procedure of microwave transistors. The noise modeling is based on a wave representation of transistor intrinsic circuit. The variable noise wave temperatures are introduced as empirical parameters of the model and their frequency dependence is modeled using polynomial regression. In that way noise temperatures can be computed for any frequency from desired frequency range yielding modeling of noise parameters with very good accuracy.
