The Keysight/Agilent/HP 8769M is an electromechanical single-pole, six-throw (SP6T) microwave switch engineered for precision signal routing in test and measurement systems operating from DC to 50 GHz. This switch delivers low insertion loss, excellent isolation, and repeatable performance across demanding automated test equipment, communication systems, and radar applications. Its long operational life exceeding 5 million switching cycles per port and low SWR characteristics make it a reliable choice for high-frequency signal distribution.
