Abstract
Abstract We propose an analog predistorter that uses a Cartesian vector modulator structure. The operation principle of the proposed predistorter is analyzed for various gain and phase characteristics. The bandwidth performance of the predistorter is presented as a function of the dominant nonlinearity order. Experiments on several power amplifiers under various test signals were performed on the proposed analog predistorter. The experimental results demonstrate that the predistorter can easily control both the gain and phase characteristics via biasing the two IM generators. © 2004 Wiley Periodicals, Inc.

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
