Abstract
Sustainability is currently becoming a trend in technologies such as telecommunications. The goal is to reduce power consumption and increase the battery life of mobile nodes. The highest power consumer in the telecommunication module, the power amplifiers were designed using inefficient configurations as the older emphasize is only to achieve highest linearity possible at the output. This work proposes designs for Class E power amplifiers operating at 2.4 GHz based on nonlinear SPICE FET models using two different Sokal’s empirical equations. One emphasizes considerations of output power with quality factor, the other does not. Clear differences can be observed through simulation results as the newer Sokal’s equation proved to be more efficient. This analytical solution can be used to design future power amplifiers where efficiency is the prime concern.
