Abstract
We study and present design guidelines for thru-reflect-line vector-network-analyzer calibration kits used for characterizing circuits and transistors fabricated on silicon integrated circuits at millimeter-wave frequencies. We compare contact-pad designs and develop fixed-fill contacts that achieve both repeatable and low contact-pad capacitances. We develop a fill-free and mesh-free transmission line structure for the calibration kit and compare it to similar transmission lines with meshed ground plane. We also develop a gold plating process that greatly improves contact repeatability, permitting the use of redundant multiline calibrations. This in turn simplifies the development of an error analysis. Finally, we apply the technique to state-of-the-art transistor characterization, and present measured results with uncertainties.

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
