Abstract
This paper describes 80-94 GHz and 70-77 GHz I-Q phase shifters and the corresponding transmitter and receiver ICs, fabricated in 65-nm CMOS and SiGe BiCMOS technologies, respectively. Lumped inductors and transformers are employed to realize small-form factor 90deg hybrids as needed in high density phased arrays. The CMOS transmitter operates with a saturated output power of +3 dBm and exhibits maximum absolute phase and amplitude errors of 14deg and 5.5 dB, respectively, when the phase is varied from 0deg to 360deg in steps of 22.5deg. The absolute phase error in the SiGe BiCMOS receiver is less than 8deg, with a maximum gain imbalance below 3 dB over its 3-dB bandwidth of 70-77 GHz. The peak gain and power consumption are 3.8 dB and 142 mW from 1.2 V supply for the CMOS transmitter, and 17 dB and 128 mW from 1.5 V and 2.5 V supplies for the SiGe BiCMOS receiver.

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
