Abstract

fetched live from OpenAlex

Most of published phased arrays are designed for aerospace and military applications.Since phased arrays has become one of the new technologies for 5G, new designs of phased array need to be carried out for 5G applications.A phased array Transmit/Receive Module (TRM) for 5G was proposed by our research group.This TRM comprises of a control MMIC and a front-end module.This thesis proposes an ultra-compact and reconfigurable X-band control MMIC, consisting of a SPDT switch, a 5-bit digital phase shifter and a 5-bit digital attenuator, for 5G phased array transceivers based on the 0.15-µm GaN HEMT process.To ensure this work is fabrication-driven design, characterization of the fabricated GaN HEMTs, in which it shows the agreements between the design kit model and measurement results, is illustrated first.Layout dimensions indicate the proposed control MMIC occupies an area size of 2 mm × 4 mm including RF and DC pads.

Direct model labels (unvalidated)

Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
