Steady-state analysis and fast optimisation of Class-E power amplifiers with lossy switch for RF choke and finite DC-feed inductance

In this work, a steady-state analysis and a fast optimisation approach based upon it are implemented to analyse the class-E PA. With this approach, the component values and performance of class-E PA with RFC and parallel-circuit load (PCL) are analysed and compared. One fast search approach is developed for various constrained/unconstrained optimisations. The analysis, fast optimisation approach and evaluation as well are implemented in Matlab©. The feasibility, flexibility and fast-simulation are shown by comparing the RFC and PCL for a 1 W class-E PA design. All the results show good match with ADS©harmonic balance.
