Abstract

fetched live from OpenAlex

This paper reports a Doherty power amplifier (PA) with significantly improved efficiency over large output power range. The efficiency enhancement is accomplished by associating digital adaptive power distribution and dynamic phase alignment mechanisms, which are implemented to prevent the efficiency degradation due to the problems of input drive waste at back-off, power-dependent phase misalignment between carrier and peaking branches, and impaired load modulation behavior. The measured average efficiency of the proposed Doherty PA is 53% compared to 45% for a standard Doherty PA.

Full frame distilled prediction

Teacher imitation

Not 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.
