The Agilent/Keysight W281DS is an in-line coaxial-to-waveguide adapter that transitions between 1.0 mm male coaxial connectors and WR-10 waveguide. Operating across the W-band from 75 GHz to 110 GHz, it enables precise measurement and characterization of waveguide devices in millimeter-wave test systems. The adapter delivers 0.7 dB insertion loss and 16 dB return loss while handling up to 10 W CW power, making it suitable for high-frequency communication systems, vector network analyzer setups, and advanced RF measurement applications requiring reliable coaxial-to-waveguide interfacing.
