Keysight 87104D Switch, SP4T, DC-40GHz, Terminated

The Keysight 87104D Coaxial Switch is a precision single-pole, four-throw (SP4T) RF switch engineered for broadband applications requiring accurate, repeatable, and reliable signal routing. Operating from DC to 40 GHz, this terminated design ensures that unused ports are properly matched, reducing reflections and improving overall system measurement accuracy.

With low insertion loss, excellent port-to-port isolation, and high repeatability across thousands of switching cycles, the 87104D is an ideal choice for automated test equipment (ATE), communications, aerospace, defense, and research laboratories. Its rugged construction and compact footprint make it well-suited for integration into complex test setups, enhancing efficiency and reducing downtime.
