Tunable Bandpass Filters With One Switchable Transmission Zero by Only Tuning Resonances
Bibliographic record
Abstract
A methodology for tunable bandpass filters (tBPFs) with one switchable transmission zero (TZ) is presented, wherein the frequency tuning and TZ switching can be simultaneously achieved by merely tuning the resonant frequencies of resonators. Theoretically interpreted by coupling matrices with arbitrary filtering orders (n ≥ 2), the TZ can be symmetrically switched between lower and upper sides of the passband while retaining the same return loss level. As a demonstration, a fourth-order waveguide tBPF is synthesized, designed, fabricated, and measured for experimental verification. Two responses, namely TZ on lower and upper sides, are showing the tunable frequency range from 9.5 to 10.8 GHz with insertion loss (IL) from 0.34 to 1.40 and 3-dB bandwidth from 230 to 370 MHz, respectively, which verifies the proposed methodology very well.

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.
