Keysight (Agilent) 8768M Multiport Coaxial Switch, DC to 50 GHz, SP5T

The Keysight (Agilent) 8768M is a single-pole, five-throw (SP5T) electromechanical coaxial switch operating from DC to 50 GHz. Built for high-performance signal routing in automated test environments, it delivers exceptional repeatability and insertion loss characteristics across its full frequency range. The switch safeguards test platforms against recalibration, downtime, and production losses—critical for communications and aerospace testing applications requiring reliable multiport switching.
