Bibliographic record
Abstract
A novel high efficiency, large output-power, 2-bit tuned mm-wave DAC realized in 45-nm SOI CMOS is demonstrated. A record breaking 24.3 dBm output power is achieved at 45 GHz with 18.3 dB saturated gain, >;14.5 V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pp</sub> differential output swing, a drain efficiency of 21.3% and 14.6% PAE. The best PAE is 22% at an output power of 23.5 dBm. Operation at 45 GHz with up to 2.5 Gbps BPSK and up to 1.25 Gbps ASK modulation is shown.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
