  • Abstract
    A noise model based on an equivalent circuit is applied to an HEMT. Besides the frequency dependence of the most important noise parameters (Fmin, Ropt, Xopt, RN) two apparent experimental facts are explained: the limited Ropt, Xopt and the increase of RN with decreasing frequency.
