Low-Cost Dielectric-Resonator Filters With Improved Spurious Performance
Bibliographic record
Abstract
A dielectric-resonator filter configuration implemented as a single piece of a high- <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">K</i> ceramic substrate is presented in this paper. The proposed filter configuration considerably reduces the cost of the assembly and the integration associated with conventional dielectric-resonator filters. A two- and four-pole filter of this type operating in the TEH <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</sub> fundamental mode have been developed, manufactured, and tested. Theoretical designs of the filters are confirmed and supported by measurement results. The wideband spurious performances of the filters are investigated and the improvement of the spurious response is demonstrated theoretically and experimentally for both two- and four-pole filters. Furthermore, a novel triplet structure based on the proposed concept is presented, which provides a new approach to implement nonadjacent couplings for the realizations of asymmetric filtering characteristics. The proposed dielectric-resonator filter configurations can be potentially used to implement dual-mode dielectric-resonator filters. The concept is very attractive for use in low-cost high- <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</i> mass production of wireless filter applications.

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.
