Dang Canh Nguyen, Oleg V. Varlamov
Abstract
The article describes a simulation model developed for switching mode envelope elimination and restoration (EER) RF power amplifiers (PA) research. A feature of the simulation model is ability to analyze the EEP PA output spectrum when it operates on a narrow-band load on a real OFDM signal fragment. The transient method of analysis and freely distributed Micro-Cup 12 environment were chosen. A number of solutions have been proposed to reduce the computation time. The adequacy of the simulation results was confirmed. Further studies suggest using this model to find solutions to ensure the ability of EER PA to operate on a narrower bandwidth load. This will expand the scope of these highly efficient amplifiers.
