Abstract
Novel X-band high-power monolithic SPST/SPDT switches in coplanar GaN technology are presented. The SPDT switch exhibits 1:6dB on-state insertion loss and better than 20dB isolation. Power handling measurements have shown that the 1dB compression point occurs with an input power equal to 38dBm at 10GHz. A combination of techniques were used to yield higher power handling while preserving low loss and high isolation. These circuit techniques include the use of stacked HEMTs to improve power handling and to minimize the loss and maintain high isolation, and also the use of a resonance inductor in parallel with the series HEMTs to improve the isolation of the switch. Simulated and experimental results are presented in support of the novel switches.

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
