Abstract
This paper presents a design methodology for high-efficiency broadband power amplifiers (PAs). The continuous class-F PA operation is extended to a contiguous set of voltage/current waveforms providing a design area for targeted drain efficiency of greater than 78.5%. The proposed methodology relaxes the design constraints by utilizing a different set of voltage waveforms in extracting the impedance design space while ensuring that the device operates below the limit of breakdown. As such, the proposed methodology provides device reliability under the broadband operation. For the experimental validation, Cree 10-W gallium nitride (GaN) transistor is used. The PA outputs more than 10W power with power added efficiency (PAE) greater than 75% with a peak PAE of 85%. This performance is achieved over the frequency band 550 to 950 MHz.

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
