Description & Specification
WR90 8.2 to 12.4GHz SMA-Female Streamlined Waveguide Adapter
X-Band Precision Transition | Flange: PBR Type: S1 | Model: WC-090-PBR-S1-SF
The WC-090-PBR-S1-SF is a streamlined 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 a compact, low-profile transition between standard WR-90 (WG16 / R100) rectangular waveguides and 50-ohm SMA-Female coaxial connections. Built with tight mechanical tolerances, it delivers an insertion loss of only 0.15 dB and a maximum VSWR of 1.25:1. Featuring a pressurized PBR flange with an integrated O-ring groove and waterproof sealing gasket (WG-90-PBR), along with a durable passivated stainless steel SMA-Female interface, it offers robust environmental protection and high RF repeatability for airborne radar, satellite communication ground stations, and outdoor microwave transceivers.
