Abstract
In this paper, we propose a realistic, accurate, versatile and thermal-free complex behavior test bed suitable for 3G power amplifier characterization. The measurement results, using the proposed test bed of a 90 W peak power amplifier based on a Motorola-LDMOS class-AB amplifier, are presented for several signals excitations (W-CDMA, CDMA2000, 8-Tones). These results show large discrepancies with those obtained by a vector network. analyzer (HP-8510C) with a CW excitation for both AM/AM and AM/PM curves. This test bed can also be used for the investigation of the memory effect in RF power amplifiers. This paper presents some measurements that point out this capability. This system has potential benefits in the area of non-linear behavior modeling of power amplifiers and synthesis of accurate predistortion function for linearization purposes.

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
