Testing high-frequency microwave and millimeter-wave systems requires components that balance rigorous electrical performance with flexible mechanical routing. Our WR-15 to 1.85mm right-angle waveguide-to-coaxial adapter efficiently transitions signals across the 50 GHz to 67 GHz V-Band frequency range. The space-saving 90-degree right-angle design allows for clean, organized cable routing in congested test racks, while precision-machined internal transitions ensure exceptional mode purity and minimal signal reflection.
