Hexa-Band Branch Line Coupler and Wilkinson Power Divider for LTE 0.7 GHz, LTE 1.7 GHz, LTE 2.6 GHz, 3.9 GHz, Public Safety Band 4.9 GHz, and WLAN 5.8 GHz Frequencies
Bibliographic record
Abstract
A hexa-band branch line coupler (BLC) and Wilkinson power divider (WPD) for long term evolution (LTE) 0.7 GHz, LTE 1.7 GHz, LTE 2.6 GHz, 3.9 GHz, public safety band (PSB) 4.9 GHz, and wireless local area network (WLAN) 5.8 GHz frequencies have been proposed, designed, implemented, and analyzed in this brief. To realize the proposed BLC and WPD a hexa-band quarter wave transmission line (TL) with complete derivation for a hexa-band operation has been introduced. A good performance for the BLC/WPD has been achieved over all the six bands with maximum 0.42/0.21 dB amplitude imbalance and 4.81°/0.9° phase deviation. Compared to the most of the existing BLCs/WPDs, the proposed BLC/WPD has simpler design structure and, compact size than the existing hexa and quad-band BLCs/WPDs.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
