Abstract
In this paper, a fully-integrated CMOS broadband RF vector multiplier (RFVM) with low root-mean-square (RMS) magnitude and phase errors and high linearity is presented. The proposed RFVM includes a three-stage RC poly-phase filter (PPF) to generate the quadrature phase signals, two parallel phase-invariant variable gain amplifiers (VGA) to adjust the amplitude and phase of the input RF signal, and a two-stage post amplifier to provide sufficient output power. Fabricated on a 0.13μm CMOS process, the RFVM demonstrator allowed for magnitude and phase control ranges of 30dB and 360 degrees over a broad operation bandwidth spanning from 0.6 to 2.8GHz. The measured root-mean-square amplitude and phase errors were limited to 0.17dB and 2.5 degrees. A high input 1-dB compression power of 3 to 5dBm was maintained over the targeted 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
