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 highpassives for fundamental and harmonic matching have been implemented. Experiments demonstrated an increase in PAE and ruggedness simultaneously even under high mismatch conditions. The amplifiers are operating in
