Power amplifier PAE and ruggedness optimization by second-harmonic control.

Second-harmonic control is applied to optimize power-added efficiency (PAE) and ruggedness of silicon power amplifiers (PAs). A differential push-pull topology is chosen because it facilitates independent fundamental load and second-harmonic control. Various amplifiers using high-Q passives for fund...
