Rectangular Waveguide-Based W-Band Eight-Way Radial Power Combiner
Bibliographic record
Abstract
For semiconductor-based W-band high-power generation, a rectangular waveguide-based eight-way power combiner was designed and fabricated, providing broadband low-loss performance. The designed power combiner consists of a four-way mode converter and an H-plane T-junction. The electromagnetic fields were rotated and equally distributed among the four waveguides of the four-way mode converter, which was perpendicular to the input waveguide. Then, the H-plane T-junctions were attached to the output waveguide of the four-way mode converter. The eight output ports were placed symmetrically with respect to the input port so that the amplitude and phase imbalances between the output ports were minimized. The power combiner was made from metal without the dielectric substrate, allowing for easy fabrication and low loss. Each dimension was optimized using three-dimensional electromagnetic simulators. The fabricated eight-way power combiner demonstrated a broadband performance such as an input return loss of less than 10 dB from 75.0 GHz to 98.7 GHz and a low loss of less than 1.0 dB from 76.7 GHz to 95.3 GHz. The minimum loss was measured as 0.6 dB from 78.8 GHz to 81.3 GHz.

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.
