Keynote 1 (Thursday, March 30)
History and State-of-The-Art in Large Signal Modeling for RF/Microwave Power Amplifier Development
Dr. Larry Dunleavy
An up-to-date survey of large signal (LS) and nonlinear models for power amplifier design will be presented, covering a wide range of device types, along with a brief history for the various categories of models. An emphasis will be placed on compact LS models for GaN, GaAs, and Silicon FET and HEMT models suitable for power amplifier design. Behavioral LS models will be presented along with advantages and disadvantages as compared to compact models. Important developments in related technologies that have had significant impact on large signal modeling, such as automated small and large signal network analyzers, wafer probe capability, and harmonic balance simulator software, will also be discussed.
Dr. Larry Dunleavy co-founded Modelithics, Inc. in 2001 to provide improved modeling solutions and high quality microwave measurement services for radio and microwave frequency circuit designers. He is currently serving as President and CEO at Modelithics. He also maintains a position as a Professor within University of South Florida’s Department of Electrical Engineering, where he has been a faculty member since 1990. In this role, he has been teaching in the area of RF & Microwave circuits and measurements for over 26 years. Prior to this he worked as a microwave circuit design engineer at Hughes Aircraft and E-Systems companies.
