Continuous Class-E Power Amplifier Modes
Artikel i vetenskaplig tidskrift, 2012

In this brief, a continuum of novel closed-form solutions is derived for class-E power amplifiers (PAs). It is analytically proven that the class-E zero voltage/zero voltage derivative switching conditions can be satisfied for an arbitrarily selected reactive second harmonic switch impedance (Z 2 S ). The higher order harmonic currents are terminated capacitively. The conventional class-E, class- E/F 2 , and class-EF 2 modes are thus subsets of the continuum. The arbitrary selection of Z 2 S enables robust waveform engineering for performance optimization in specific applications. Furthermore, the theoretical derivation provides important possibilities for wideband class-E PA synthesis. © 2004-2012 IEEE.
