Abstract
To alleviate practical limitations in the design of millimetre‐wave on‐chip image‐reject filters, systematic design methodologies are presented. Three low‐order filters with high‐selectivity and low‐loss characteristics are designed and compared. Transmission zeroes are created by means of a quarter‐wave transmission line (filter 1) and a series LC resonator (filters 2 and 3). Implemented on silicon germanium, the filters occupy 0.125, 0.064 and 0.079 mm 2 chip area including pads. The measured transmission losses across 81–86 GHz E‐band frequency range are 3.6–5.2 dB for filter 1, 3.1–4.7 dB for filter 2 and 3.6–5 dB for filter 3 where rejection levels at the image band are >30 dB.

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
