Description & Specification
WR-90 Waveguide to Coaxial Adapter
X-Band Series | 8.2 GHz – 12.4 GHz | SMA-Female
The WR-90 Waveguide to Coaxial Adapter is a high-precision RF component professionally engineered for X-band applications. Spanning the 8.2 GHz to 12.4 GHz frequency range, this adapter enables high-efficiency power transition between waveguide transmission lines and coaxial systems. Featuring a standardized UG-39/U (UBR) flange and a precision Stainless Steel SMA-Female connector, it is designed to maintain exceptional Signal Integrity with a low average V.S.W.R of 1.3. This industrial-grade component is essential for radar installations, satellite communication ground stations, and high-frequency laboratory measurement environments.
