The Keysight (Agilent) 8767M is a single-pole, four-throw (SP4T) electromechanical coaxial switch engineered for precision signal routing across DC to 50 GHz. Built on solenoid-driven actuation with dual coil windings, this switch delivers exceptional repeatability—typically less than 0.03 dB to 50 GHz—and rated mechanical life of minimum 5 million cycles per port. The 8767M handles average RF input power to 1 Watt and peak power to 100 Watts, making it suitable for laboratory, production test, and automated measurement systems requiring high reliability and deterministic switching performance.
