The Keysight 87106A is a high-performance multiport SP6T terminated coaxial switch designed for microwave and RF instrumentation. Operating from DC to 4 GHz, it provides exceptionally low insertion loss, high isolation, and outstanding repeatability over a minimum lifetime of 5 million cycles. It is ideal for routing signals in automated test equipment (ATE) systems, communications systems, and general-purpose RF signal routing applications.
