Abstract
A compact, low loss and wide coverage impedance tuner using alumina-based integrated passive device (AIPD) technology is proposed. By integrating a tuning element-barium strontium titanate (BST) varactor, with high-Q AIPD L-C elements, an impedance tuner with wide impedance coverage range is achieved while maintaining low insertion losses. Details of the in-house AIPD fabrication process are presented. Measured results for a continuous impedance tuner designed at 2.5 GHz are presented demonstrating a maximum insertion loss of 1.2-dB impedance tuner from 2-3 GHz. The overall footprint of the chip is only 3.8 mm × 1.88 mm.

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
