A new; simple large signal model for high power HBTs and BJTs suitable for CAD tools is proposed and experimentally evaluated. The major features of the model are that main model parameters are determined directly from measurements in typical operating conditions and that the model exhibits good convergence properties. The model was evaluated with extensive DC; S parameter; and power spectrum measurements. Good correspondence was obtained between measurements and simulations.
