A compact size reconfigurable 1- 3 GHz impedance tuner suitable for RF MEMS applications
Bibliographic record
Abstract
This paper proposes a novel spiral topology for a reconfigurable stub tuner with radio-frequency micro electro mechanical system (RF MEMS) switches. The flexibility of the configuration permits the transformation from single to double and triple stub tuning covering a wide range of impedance values. Moreover, the number of switches present in the tuner dictates the range of loads to be matched. The design produces 2048 different impedances. The design of a spirally rolled parallel coplanar waveguide (CPW) transmission line tuner is presented along with simulation results. The proposed tuner provides real-time reconfiguration and matching for RF loads that could change during system operation. Real time intelligent algorithm would be used to control electronically the tuner. This proposed design would be used for military and high performance circuit applications for future low-cost and low-power intelligent RF micro systems and systems-on-chip.

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.
