The Keysight P9404A is a Single Pole, Four Throw (SP4T) PIN solid-state switch engineered for high-speed RF and microwave switching across 100 MHz to 8 GHz. Built for instrumentation, communication, and radar systems, it delivers sub-450 nanosecond switching speed, port-to-port isolation exceeding 80 dB, and 2.5 dB insertion loss at 4 GHz. The extended operational life minimizes maintenance overhead in high-volume manufacturing and automated test environments.
