Abstract
Millimeter-wave (mmW) Y-junction ferrite circulators above 40 GHz have limited bandwidth due to the lack of ferrite materials having a high saturation magnetization above 5000 G and the simple and traditional circuit design approaches that cannot produce wideband circulators in this frequency range. To increase the bandwidth of mmW Y-junction ferrite circulators, novel design techniques for such circulators should be developed to achieve a functional circulator over a wide bandwidth at mmW frequencies. In this article, a Y-junction ferrite circulator is proposed, which is based on the WR15 waveguide standard with broadband performance for 60-GHz inter-satellite communications. An approximate design procedure for the core section of the proposed circulator is presented. The proposed Y-junction ferrite circulator achieves more than 20% bandwidth centered at 60 GHz. In addition, the effect of input power and ambient temperature on the performance of the circulator is studied for an input power of 300 W and ambient temperature in the range from −80°C to 80°C. The experimental prototype is fabricated and measured, where the measured response is in very good agreement with the numerically anticipated counterpart. The fabricated circulator achieves beyond −17 dB matching level with −15 dB isolation and 1-dB insertion loss over the entire bandwidth of interest.

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
