Thermal Effect on Wideband Harmonic Generation for Future Wireless Sensing
Bibliographic record
Abstract
The stability of an SMS7630 diode's harmonic output spectrum under the fluctuation of operating temperature and frequency is analytically and experimentally investigated in this work. Measurements were conducted between <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$-40^{\circ} \mathrm{C}$</tex> and 80°C while the diode was powered by a 7 dBm input power at <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$1 \pm 0.05 \text{GHz}$</tex>. Stability and performance drifting effects were assessed by analyzing the output spectrum, which includes the fundamental frequency as well as its first and second harmonics. Results show that the diode behaves consistently (<tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\pm \mathbf{1 ~ d B m}$</tex> in average) under a variety of operating temperature, underscoring its dependency on real-world usage in temperature-variable environments.

How this classification was reachedexpand
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.
