The WC-090-UBR-E2-NF is a high-precision, industrial-grade Endlaunch Rectangular Waveguide to Coaxial Adapter expertly engineered for multi-octave microwave transitions across the 8.2 GHz to 12.4 GHz frequency band. This premium component transitions seamless energy propagation from standard WR-90 (WG16 | R100) waveguide profiles into a high-grade N-Female interface. Delivering an ultra-low insertion loss of just 0.15 dB and a maximum VSWR threshold of 1.25, it guarantees unparalleled signal transmission integrity for laboratory spectrum calibration, radar links, and high-power satellite testing benchmarks. Supporting power profiles up to 150W (CW) and 3KW peak capabilities, this robust waveguide unit is engineered and manufactured in Taiwan to exceed extreme industrial measurement certifications.
