Abstract
This paper proposes a new digital baseband predistorter architecture for 3G RF power amplifiers. The proposed architecture compensates for temperature drifts using a simple temperature sensoring feedback path coupled with a temperature dependant predistortion function. The proposed predistorter is composed of a static look-up table in parallel with an adjustment module that implements the temperature compensation function. Measured AM/AM and AM/PM characteristics of 100-W peak envelop power LDMOS power amplifier were used to evaluate the performances of the proposed predistorter. The results show 15 dB improvement in the intermodulation distortion level at the power amplifier output under a CDMA2000 SR3 excitation. This improvement was maintained for amplifier's case temperature variations between 25degC and 45degC.

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
