Abstract
Abstract In this article, we compare several concepts for gallium‐nitride (GaN) power high electron mobility transistor (HEMT) packages in terms of their drain‐to‐source parasitic inductance and resistance values. Unlike in previous studies, however, due to several fast transient use cases the investigated frequencies are extended to 2 GHz. Since the device's dimensions are already a significant fraction of the corresponding wavelength at 2 GHz, full wave simulation tools have been employed to more accurately assess the problem. The results reveal how the considered package concepts affect the overall parasitic device impedances and show a clear improvement of the parasitic impedance over each generation of package implementation. Furthermore, full wave analysis results are compared to method of moments results to emphasize the necessity of full wave simulations at these frequencies.

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
