Abstract :
This paper presents a comprehensive set of design rules for highly efficient power amplifiers driven by low voltage supplies. Optimum conditions for active device conduction angle and load impedance terminations at the fundamental and 2nd and 3rd harmonics are derived from theoretical and nonlinear simulation studies. Then, these rules are validated by the construction of a 3V inverse class F MMIC power amplifier.
