Abstract

This paper describes a design methodology based on waveform engineering within a harmonic active load-pull system and utilizing the Cardiff Direct Look-Up Table (DLUT) model. The process seeks to address some of the key issues facing designers when using nonlinear simulation of high power microwave amplifiers: model validity, boundary conditions and yield. The application of this process to the design of a 0.5 W, 5-10 GHz GaAs pHEMT with good PAE is detailed.
