Millimeter-Wave Ultra Wideband Multilayer Superconducting Filter
Bibliographic record
Abstract
Ultra wideband (UWB) millimeter-wave filters are needed in the realization of analog front ends of superconductor digital receivers. In this paper, a multi-layer niobium-based superconducting bandpass filter operating over the frequency range 30-60 GHz is demonstrated for the first time. The filter is realized in a co-planar waveguide structure, where cross-overs in the multilayer structure are employed to reduce the filter size. The paper also illustrates how these cross-overs can be utilized to fine tune the filter performance. An 8-pole superconductor niobium-based filter with a size of 0.88 × 2.2 mm designed with a center frequency of 45 GHz and a bandwidth of 30 GHz has been developed, fabricated, and tested. The results demonstrate the feasibility of monolithically integrating UWB millimeter-wave filters with a superconductor receiver on single-chip.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
