The Agilent/Keysight W281D is a right-angle waveguide-to-coaxial adapter that transitions WR-10 waveguide signals to 1.0 mm male coaxial connectors. Operating across W-Band from 75 GHz to 110 GHz, this adapter enables seamless integration of waveguide and coaxial components in test systems. Precision engineering delivers maximum SWR of 1.16, minimizing mismatch uncertainty and ensuring reliable measurements.
