High-Temperature Fully Integrated Wireless Monitoring Systems for Aerospace Applications
Bibliographic record
Abstract
This paper presents a fully integrated data transmission system utilizing gallium nitride (GaN) high-electron-mobility transistors (HEMTs). The system is specifically designed for high-temperature (HT) applications, with a focus on pressure and temperature sensors for aerospace purposes where the environmental temperature can surpass 400 °C. The proposed system comprises a front-end amplifier with a gain of 20 V/V to amplify the sensed signal, followed by a novel analog-to-digital converter (ADC) that drives a modulator employing the load-shift keying technique. An oscillation frequency of 1.5 MHz is employed to ensure robust wireless transmission, even through metallic barriers. To retrieve the data, a new demodulator architecture based on a half-bridge rectifier is introduced. The fabricated system is implemented on an 11 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> silicon carbide (SiC) substrate and experimentally validated at a temperature of 25 °C, while certain digital core circuits demonstrate stable operation at HT conditions up to 400 °C.

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.
