Abstract
We present the design, fabrication, and experimental testing of bandwidth-reconfigurable surface acoustic-wave (SAW) filters with integrated vanadium dioxide (VO2)-based radio frequency (RF) switches. We propose a design that utilizes the phase-change properties of VO2, which transitions between insulating and conductive states to enable dynamic reconfiguration of the SAW filter bandwidth. By modifying the interdigital transducer (IDT) configurations, the electromechanical coupling coefficient (k2) of the resonators can be varied, thus enabling the reconfiguration across different bandwidths. Experimental results demonstrated the bandwidth adjustability offered by the proposed design, and the fabricated prototype filters suggested that monolithically integrated VO2-based RF switches can provide a flexible solution for reconfigurable acoustic filters. To the best of our knowledge, this work represents the first demonstration of bandwidth-reconfigurable acoustic filters with monolithically integrated RF switches with acoustic resonators.

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 it
