A novel compact three-dimensional CMOS branch-line coupler using the meandering ECPW, TFMS, and buried micro coaxial technologies at 60 GHz
Bibliographic record
Abstract
This paper proposes a new approach for realizing a compact 3-D 90#x00B0; hybrid coupler incorporating compact meandered elevated coplanar waveguides (ECPW), thin-film microstrip (TFMS) transmission lines, and micro coaxial shunt stub loading. The design technique has been successfully demonstrated using a multi-layer 90nm CMOS process. The proposed coupler takes advantage of the multi-level metallization processes offered in CMOS technology. The intrinsic area of the fabricated 3-D hybrid coupler is significantly reduced with a size reduction of 81% in circuit area at 60 GHz as compared to that of a conventional hybrid coupler using the ECPW/TFMS configuration. Simulated and experimental results are presented in support of the novel miniature coupler

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
