Abstract
A design methodology for multioctave RF power amplifiers (PAs) is presented in this brief using sequential harmonic characterization. The investigation of in-band harmonics on the multioctave performance of the RF PA shows that a more optimal performance can be achieved using the proposed technique compared to the conventional load-pull. To demonstrate the capability of this technique, a broadband multioctave PA prototype was designed and fabricated using sequential second harmonic characterization. The fabricated prototype uses a GaN HEMT from Cree Inc. and exhibits a drain efficiency of 53%-64% in the range of 0.7-4.0 GHz while having an output power of 37.5-39.1 dBm corresponding to the fractional bandwidth of 140%. Measurement results validate the proposed method as a robust PA design procedure for broadband and multistandard applications.

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
