For realizing wideband class-F power amplifiers (PA), geo-electrical analysis methods are introduced to determine the best design parameters in a simpler way than relying on computer-guided optimization. The fabricated class-F PA at 1.9 GHz demonstrated a peak efficiency of 80.5% and a bandwidth of 750 MHz for an efficiency of more than 63%. It is presumed that the optimization increased the bandwidth by 10%.
