The Agilent/Keysight 8764B/33313B is a 5-port coaxial electromechanical switch for signal routing across DC to 18 GHz. Built on solenoid actuation, it delivers insertion loss under 0.20 dB to 2 GHz and under 0.5 dB to 18 GHz, with isolation exceeding 90 dB across the full frequency range. Switching completes within 20 milliseconds and maintains repeatability better than 0.03 dB typical. The switch endures over 1 million cycles, making it suitable for high-volume automated test and measurement systems requiring signal integrity and long operational life.
