Abstract
The design considerations and circuit topologies of a family of ultralow-power fundamental-frequency and second-harmonic 60-GHz radar sensors are described. The single-chip sensor architecture features four lownoise-matched receivers, either a fundamental-frequency 60GHz voltage-controlled oscillator (VCO) or 30-GHz VCO + doubler, and a static divide-by-8192 chain which is turned OFF 95% of the time to save DC power. On-die measurements show a power consumption of 42 mW from a single 1.2-V supply, 10% frequency tuning range, -104 to -108 dBc/Hz phase noise at 10-MHz offset, 10-dB conversion gain per receiver, and -7-dBm transmitter output power at the antenna pads. Several 45-nm SOI-CMOS sensor dies were flip-chip mounted on a 7 × 7 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> flexible interposer which also includes four receiveand two transmit antennas. Doppler and direction of arrival tests were conducted over distances of several tens of centimeters.

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
