Abstract

fetched live from OpenAlex

Abstract In this article, we present an optimized Doherty power amplifier using an unequal quadrature input splitter and bias control for the peaking amplifier. The linearity and efficiency performances of the Doherty power amplifier were experimentally optimized by means of unequal quadrature input power splitters, which drive unbalanced input power between the carrier and peaking amplifiers. The bias points of the peaking amplifier were also adjusted for each input splitter. A high power‐added efficiency of 33.68% and an output power of 33.95 dBm were achieved for a down‐link wide‐band code division multiple access signal excitation at a given adjacent channel leakage‐power ratio of −30 dBc. This was a significant improvement by 2.75% and 8.22% points from the conventional Doherty and class‐AB amplifiers, respectively. © 2008 Wiley Periodicals, Inc.

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.
