Power Amplifier DesignAccurate Simulation Models Yield High Efficiency Power Amplifier Design Sonoko Akamatsu, Charles Baylis, Dr. Larry Dunleavy Contact: Larry Dunleavy, Dunleavy@eng.usf.edu, (813)974-2574 The design of RF & microwave power amplifiers continues to be somewhat of an art yet to be reduced to a systematic repeatable design practice on a wide-scale basis, despite the many excellent treatments of the subject in the literature, text books (e.g. [1]), and a number of courses. The general unavailability of sufficiently accurate and reliable nonlinear models for power transistors has been a major factor in limiting the accuracy of power amplifier (PA) simulation results. Suitable nonlinear models must properly treat the nonlinear and combined DC/AC analysis required for proper power compression and ef……
