Description & Specification
WR-90 Waveguide to Coaxial Adapter
Precision X-Band Transition | Standard UG-39/U Flange | 8.2 GHz – 12.4 GHz
This WR-90 Waveguide to Coaxial Adapter is a high-precision RF component professionally engineered for demanding X-band applications. Spanning the 8.2 GHz to 12.4 GHz frequency range, this precision component enables high-efficiency power transition between waveguide transmission lines and coaxial networks. Featuring a robust, standardized UG-39/U (UBR) flange interface and a premium Stainless Steel SMA-Female connector, it is structurally optimized to maintain exceptional Signal Integrity with a low average V.S.W.R profile of 1.3 : 1 and a maximum rating of 1.5 : 1. Fully designed and manufactured in Taiwan, this industrial-grade adapter safely handles up to 200 Watts of continuous wave power, serving as an essential link for radar installations, satellite communication ground stations, and advanced high-frequency microwave laboratory measurements.
