Broadband Ortho-Mode Transducer for high performance modular feed systems
Bibliographic record
Abstract
A high performance broadband Ortho-Mode Transducer (OMT) design with more than 70% bandwidth is based on a novel branching concept with a two-fold symmetric structure. A symmetrical pair of ridge waveguides is facing the common branching region serving one polarization. The orthogonal polarization is coupled by a symmetrical pair of probes associated with coaxial interconnections. Folded Magic Tees are implemented for the re-combination of the semi signal portions of the ridge waveguides and the coaxial interconnections, respectively, to serve the complete signal at the dedicated interface ports. (To overcome the bandwidth limitation of rectangular waveguide solutions, tailored ridge waveguides have been established for the interfacing and internal waveguide interconnections.) This broadband OMT is foreseen as the key building block in a modular feed system approach employed for high capacity data transmission with large radio antennae. The measured characteristics validate the design concept with the required high performance properties that are necessary for these outstanding applications.

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.
