Abstract
A new E-plane quasi-optical waveguide power amplifier with an innovative low-loss integrated transition array of finline and microstrip is presented, which employs a concept of TEM mode waveguide. This TEM waveguide was proposed on a patterned surface or usually called uniplanar compact photonic bandgap (UC-PBG) structure. Our Ku-band back-to-back transition array demonstrates a return loss better than -17.5 dB and an insertion loss better than -0.65 dB. The TEM waveguide is found to have a 1 GHz bandwidth centered at 14.5 GHz. The use of such a frequency-selective surface has showed that one could implement more power cards inside this TEM waveguide. The space power combiner is used to combine the output powers of twelve 20 mW MMIC amplifier chips. The power module yields a 21.08 dBm output power including the loss of transition and a combining efficiency of 89% is observed in this work.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
