Abstract
The paper extends the concept of waveform shaping for back-off applications which can be applied to realize power amplification sub-blocks in load modulation based power amplifiers. The proposed theory starts with deriving the intrinsic current and voltage waveforms as a function of output power back-off factor. Thereafter, a design methodology is proposed to optimize the performance of power amplifier for back-off requirements within a limit of 3 dB gain compression. For experimental validation, the implementation is carried out using a 1.95 mm gallium nitride (GaN) die. The single-ended PA is designed to operate as a carrier PA in a 35 dBm average asymmetric Doherty configuration (44 dBm peak power). The PA exhibits a drain efficiency of 78% at an average output power of 35 dBm at a frequency of 2.6 GHz.

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
