The Agilent/Keysight 8764B is a 5-port coaxial switch engineered for precision signal routing from DC to 18 GHz. This mechanical-latching switch delivers exceptional isolation exceeding 90 dB across its full frequency range, with insertion loss below 0.20 dB to 2 GHz and below 0.5 dB to 18 GHz. Built for high-cycle applications, it exceeds one million operational cycles while maintaining repeatability within 0.03 dB typical.
