Abstract

This paper considers a new approach for nonlinear system level models dedicated to high RF power amplifiers. The constant increase of power density imposes to take into account of thermal effects. In this framework, a new electro-thermal behavioral model based on the coupling between a behavioral electrical model and a thermal reduced model predicting the operating temperature of the amplifier is expressed for radar application. This model has been successfully implemented into the Agilent Advanced Design System (ADS) circuit simulator. The transient thermal effects have been simulated thanks to an envelope transient analysis.
