Abstract
A dual-band matching network using dual-band coupled line based quarter-wave line is presented. The proposed matching network is capable of providing simultaneous match for frequency-dependent complex loads having different values at two arbitrary frequencies to Z <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> (here, 50Ω). A very simple step-wise evolution of the transformer is shown and closed form design equations are obtained. It is to be noted that since matching networks are usually part of larger systems such as amplifiers, it is customary in literature to show working of such design using simulators. Agilent ADS is used to verify the proposed network. A very good result is obtained confirming the theory. Although, here the discussion is in RF amplifier context, such a transformer will also be of interest to other designers such as designers of mixers and antennas.

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
