Investigation of the Effect of Weak Non-Linearities on P1dB and Efficiency of Class B/J/J* Amplifiers.

The variation of phase of the current through the non-linear intrinsic capacitances of a high-power RF device caused by the variation of the phase in the continuum of drain voltage waveforms in Class B/J/J* leads to a reduction of intrinsic drain current when moving from class B to class J* while the drain current increases from class B to class J. Consequently, a subset of voltage waveforms of th...
