The Keysight (Agilent) 8769M is a Single Pole, Six Throw (SP6T) electromechanical coaxial switch that routes signals from DC to 50 GHz with exceptional reliability. Built for high-frequency test and measurement in communications and aerospace applications, the 8769M delivers insertion loss under 3.4 dB at 50 GHz and repeatability better than 0.03 dB typical. Its solenoid-driven design uses self-interrupting contacts to minimize power draw and simplify driver circuits, while permanent-magnet armature retention ensures durability exceeding 10 Gs shock.
