A Low-Loss Ka-Band Distributed Metal-Air-Metal MEMS Phase Shifter
Bibliographic record
Abstract
A 4-bit wideband distributed phase shifter has been developed for Ka-band operation. The design results show that the digital shifter has four basic phases of 11.25, 22.5, 45, 90 and thus 16 kinds of phase states can be constructed from the combination of them. The simulation results also demonstrates that the insertion coefficient is better than -1.37 dB, the phase error is less than 3.983 at 30GHz, and the reflection coefficient is lower than -10dB from 25GHz to 35GHz for each state. This low-loss distributed metal-air-metal MEMS phase shifter can be well applied to phased arrays. Streszczenie. W artykule opisano 4-bitowy szerokopasmowy przesuwnik fazy zaprojektowany do pasma Ka. Przesuwnik ma cztery ]glowne fazy: 11.25, 22.5, 45, 90 i 16 kombinacji miedzy nimi. Bląd jest mniejszy niz 3.983 przy 30GHz.

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; both teacher heads agree on what is shown here.
