Description & Specification
WE-90-DA WR-90 1/2 to Standard Waveguide Adapter
X-Band Precision Waveguide Transition | 8.2 - 12.4 GHz | Model: WE-90-DA
The WE-90-DA is a precision X-band half-height to standard rectangular waveguide 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 spectrum, it provides an efficient and seamless transition between 1/2 height WR-90 waveguides and standard full-height WR-90 waveguides. Designed with tight mechanical tolerances, it delivers an ultra-low insertion loss of 0.15 dB and a maximum VSWR of 1.25:1 with exceptional repeatability. Featuring a precision CNC machined aluminum body with an integrated 1/2 D3 flange and standard UBR90 square flange, it is an essential component for radar assemblies, satellite communication systems, and laboratory microwave metrology.
