Abstract
Frequency converters using pumped nonlinear conductance and pumped nonlinear capacitance with the property of signal flow in one direction only are the subject of this thesis. The unilateral property can be obtained either by a suitable termination at the image frequency or by quadrature pumping the conductance and capacitance. Of great importance is a frequency converter in which the output frequency is lower than that of the input. Such a down—converter based upon a proposed image termination method is examined both analytically and experimentally. Conditions are given which the conductance and capacitance must satisfy in order that the image termination be passive. The conditions are fulfilled by a single tunnel—diode. It is found that a forward- to reverse-gain ratio of at least 20 db over a 5% bandwidth is feasible; the estimated noise figure is 3.4 db. The quadrature pumped converter is compared with the image terminated converter and it is shown in particular that the former can be unilateral only at one frequency.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
