Abstract
The instantaneous quadrature technique is an efficient tool for nonlinear behavioral-level simulation of RF/microwave circuits or systems over wide frequency and dynamic ranges. In order to obtain accurate simulation results, accurate approximation/representation of the nonlinear transfer functions (or factors) as well as accurate measurement (or circuit-level simulation) of the amplitude (AM–AM) and phase (AM–PM) nonlinearities are required. In this paper, we consider how to approximate these transfer functions (factors) using splines, orthogonal and nonorthogonal series expansions, and evolutionary programming techniques (genetic algorithm and neural networks) with viewpoint of the simulation accuracy. The influence of AM–AM and AM–PM measurement (or simulation) inaccuracy and noise on the entire simulation accuracy is also discussed. Series expansion methods are proposed as a tool to filter out the measurement noise. © 2000 John Wiley & Sons, Inc. Int J RF and Microwave CAE 10: 238–252, 2000.

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
