✦ Synopsis

Power-amplifier class-F operation is investigated and revised, evidencing the fundamental importance of the harmonic-generating mechanism and the limitations imposed by the device input and output nonlinearities on the ideal class-F behavior. Closedform expressions are derived for the major design quantities, together with the optimum fundamental and third-harmonic loading of the active device. A design procedure, making use of the derived expressions, is presented and the deviations from the ideal behavior are discussed. Sample designs, making use of a full nonlinear device model and commercial analysis software, are carried out to demonstrate the effectiveness of the analysis and the design procedure. It is shown, both analytically and using commercial nonlinear simulations, that blind application of commonly used, idealized class-F harmonic terminations can cause unexpected detrimental results.
