An increased power efficient switching mode power amplifier system. The system includes a SMPA and an E/S reactive component. The SMPA includes a transistor, an RF choke and a tank circuit. The transistor has an emitter/source and is capable of receiving an input signal. The RF choke is operatively coupled to the transistor. The tank circuit is operatively coupled to the RF choke and the transistor. The E/S reactive component is operatively coupled to the emitter/source of the transistor of the SMPA. The E/S reactive component has a desired E/S degeneration reactive component value. A method for an increased power efficient switching mode power amplifier system is also described.
