➋
DESIGN
•
Consists of an orthomode junction (OMJ) feeding
a circular, open-ended or corrugated aperture
•
OMJ based on a quad-ridge circular waveguide
with external feeding circuits
•
OMJ feeds directly into a circular waveguide
providing wideband performance
•
Electrical symmetry for mono-mode excitation
enforced by balanced feeding on a 1:3
bandwidth
➌
REPEATABILITY
•
Stiff and robust mechanical design
•
Precision machined
•
High reliability connectors
•
High reliability of external components
