Abstract

fetched live from OpenAlex

A LlNC amplifier with perfectly balanced branches and a Chireir-outphasing combiner is studied and the sources of its nonlinearity are identified. A phase-only predistortion function is derived in explicit form and used to linearize this amplifier. The predistortion function preserves constant envelope operation of the amplifiers. The impact of the predistortion function on the combiner efficiency is also investigated. It is found, through simulation with a CDMA signal that the predistortion function linearizes perfectly the amplifier. It is also shown, that with perfect linearity, the efficiency of Chireix-outphasing amplifier reduces to that of the LINC amplifier with a resistive combiner.

Full frame distilled prediction

Teacher imitation

Not 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.
