Abstract
This paper analyzes the power losses in distributed multiharmonic matching networks and proposes a methodology to minimize these losses, which are critical in designing harmonic controlled or switching mode power amplifiers (PAs). The effect of the harmonic output matching topology on PA performance is studied. An analytical evaluation is developed to show the effect of the harmonic network topology on the conduction losses in the fundamental matching network. This analysis is validated through the comparison of two different matching network topologies in the design of an inverse class F PA with a carrier frequency of around 1 GHz. A 0.2-dB improvement in the losses is achieved, allowing for an improvement of the output power and gain and for an increase in the power-added efficiency by 4%, reaching 81%.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
