Large-signal nonlinear analysis of a high-power high-frequency junction transistor

A relatively complex nonlinear model is derived for large-signal analysis of high-power high-frequency junction transistors. The model, based on a modified Ebers-Moll equivalent circuit, is particularly useful when the transistor operates as a high-speed switch and is generally either ON or OFF, and seldom in between, or ACTIVE. A digital computer program NET-1 is used for transient analysis of the model.
