Agilent/Keysight V281DS

The Agilent/Keysight V281DS is an in-line coaxial-to-waveguide adapter that bridges 1.0 mm coaxial connectors to WR-15 waveguide for V-band measurements. It enables direct interfacing between coaxial test equipment and waveguide devices operating across the 50 GHz to 75 GHz spectrum. The adapter delivers 0.7 dB typical insertion loss with 16 dB typical return loss, supporting continuous wave power up to 10 W.
