Abstract
This paper presents a fully reconfigurable dual-mode bandpass filter based on substrate integrated circular cavity technique (SICC). Dual-modes are excited orthogonally for miniaturization, which can be mutually coupled by the use of a cavity perturbation technique. Varactor diodes are used to tune cavity resonant frequencies independently since the arranged tuning units are only set for affecting one of the related modes. Combining controlled external coupling, all parametric tunings are achieved such as center frequency, bandwidth, transmission zero and other reconfigurable filtering characteristics. On the basis of tunable resonant frequencies, quasi-elliptical, linear phase and intrinsic-switching capability are obtained. For an experimental validation of the proposed structure, a dual-mode bandpass filter was fabricated and measured. As one example of the quasi-elliptical response, a constant absolute bandwidth of 200 MHz in the tuning range 2.83-3.55 GHz with insertion loss of 1.76-5.08 dB is observed in our experiments.

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.
