Analysis of miniaturized 3 dB branch-line hybrid couplers using distributed MIM capacitors
Bibliographic record
Abstract
This letter presents the trade-off between size reduction and electrical performance of miniaturized branch line couplers using distributed capacitors placed in the inner open area of the hybrid. Based on single, double, and triple II-section approximations of the quarter wavelength transmission lines of a conventional design with high impedance lines and shunt metal-insulator-metal (MIM) capacitors, size reduction as well as electrical performance are compared both in simulation and experimentally. The miniaturized triple-section hybrid achieves similar bandwidth performance as the conventional 3 dB branch line hybrid coupler, but with a 61.2% smaller footprint. © 2010 Wiley Periodicals, Inc.

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.
