摘要: The new inverse class F operation mode for high-efficiency power amplifiers is analyzed. Unlike regular F, it requires an open circuit termination at the second harmonic and a small impedance third harmonic. features higher PAE than but transistors with breakdown voltages. A study performed using waveform measurement technique in conjunction active/passive load-pull system showed PAE=83% compared to PAE=64% F. measured results are good agreement analytical prediction.
