Micro-Apps 2013: Class F Power Amplifier Design, Including System-to-Circuit-to-EM Simulation

Class F Power Amplifier Design, Including System-to-Circuit-to-EM Simulation

Mark Saffian, AWR Corporation

Power amplifiers (PAs) used in today’s complex wireless system designs cannot always be modeled accurately using traditional steady-state techniques such as harmonic balance. Dynamic time-domain analysis is moving to the forefront as designers are adopting simulation techniques such as modulated bias to better understand how their amplifiers perform under actual operating conditions. This presentation highlights a Cree Class F PA reference design using a GaN HEMT device, and shows a complete analysis of the design using AWR's harmonic balance simulator and AXIEM® 3D planar EM simulator for the large tuning structures, as well as AWR’s Circuit Envelope technology for full system level analysis.
