Abstract
This paper reports two configurations of non-volatile multiport transfer switches based on the phase change material (PCM) germanium telluride. The monolithic transfer switches are developed in-house using a custom microfabrication process designed to operate over a wideband dc-30GHz. A C-type switch configuration is presented with two operational states in a highly miniaturized package with the device core area under 0.09mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . A unique, highly versatile multiport R-type switch configuration is proposed with three operational states that offers improved system flexibility, reducing the number of switches for routing. The R-type switch configuration has a device core periphery under 0.2mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The presented devices are compared with the current state-of-the-art switch technologies. The transfer switches exhibit a measured insertion loss of less than 1.5dB, return loss better than 18dB, and +35.5dBm measured power handling capability with switching speed less than 2 μs.

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
