A Novel Design Method of Highly Efficient Saturated Power Amplifier Based On Self-Generated Harmonic Currents

A novel design method without requiring the special harmonic termination circuit for a highly efficient power amplifier (PA) is proposed. The proposed PA is driven into saturated operation, from the linear to knee region, by adjusting the only fundamental load, and the saturated operation induces self-generated harmonic currents. The current and voltage waveforms can be shaped easily by the har... » read more
