Abstract
A power combined high-efficiency oscillator is proposed using a hybrid class E and class F tuning, where the odd harmonics are shorted: the class E/F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">odd</sub> . The oscillator is achieved by adding a high-pass feedback network to a class E/F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">odd</sub> amplifier, where the output's odd harmonics are used to construct the required square-like wave at the input. Furthermore, two class E/F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">odd</sub> oscillators can be power combined using a distributed active transformer, where magnetic coupling to the high-pass feedback network can be realized using a third transformer winding. Two power combined class E/F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">odd </sub> oscillators designed using this method have an oscillation frequency of 10.1 MHz, a total output power of 324 W and dc-to-RF conversion efficiency of 75%.

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
