Abstract
Multiplexers play an important role for radio frequency combination and separation in various communication systems and remote sensing systems. In recent years, continuous innovations in computational intelligent algorithms have significantly advanced the development of multiplexer synthesis methods, especially in coupling matrix optimization and topology design. This article provides a comprehensive overview of methodologies for multiplexer synthesis and offers a complete design guide for multiplexers. It conducts a comparative analysis of different synthesis methods, providing practical guidance and suggestions for problems in various scenarios, which helps designers choose the appropriate approach based on application requirements. The focus of the article is on reporting several optimization-based techniques for coupling matrix synthesis. Then, a novel topology designed based on the optimized synthesis approaches is reported. Furthermore, the study explores channel frequency allocation schemes relevant to this new topology, thereby expanding the design boundaries of multiplexer topologies.

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
