Abstract
This paper presents a 370-410-GHz phased-array transmitter, which is based on a W-band distribution network, amplifiers, and vector modulators, feeding a linear eight-element quadrupler array. The quadrupler outputs are connected to high-efficiency microstrip antennas. The design is scalable to a large number of elements, since most of the chip operates at W-band frequencies. The chip is built using 45-nm CMOS silicon on insulator technology, which offers transistors with ft and fmax of 250-260 GHz referenced to the top metal. The phased array results an equivalent isotropic radiated power (EIRP) of 5 dBm at 375-405 dBm with a peak EIRP of 7-8.5 dBm at 380-400 GHz and with a pattern scan of +/-35° in one plane. To the best of our knowledge, this is one of the first demonstrations of a phased array operating at 400 GHz using CMOS technology and with wide operating bandwidth.

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
