Description & Specification
WR90 8.2 to 12.4GHz SMA-Female Waveguide Coaxial Adapter
X-Band Right-Angle Precision Transition | Flange: UBR | Model: WC-090-UBR-SF
The WC-090-UBR-SF is a precision X-band rectangular waveguide to coaxial adapter professionally engineered and manufactured by Fei Teng Wireless Technology Co., Ltd. (FT-RF) in Taiwan. Operating across the 8.2 GHz to 12.4 GHz frequency range, it provides an efficient and low-loss right-angle transition between standard WR-90 (WG16 / R100) rectangular waveguides and 50-ohm SMA-Female coaxial connections. Built with tight mechanical tolerances, it delivers a low maximum VSWR of 1.25:1 with exceptional repeatability. Featuring a compact aluminum body with an integrated square UBR flange (compatible with UBR100 / FBP100 patterns) and a passivated stainless steel SMA-Female connector, it handles up to 50W CW / 500W Peak power, serving as a dependable component for satellite communications, microwave links, and precision laboratory RF measurements.
