Agilent/Keysight U9424A

The Keysight U9424A is a Single Pole Four Throw (SP4T) solid-state FET switch engineered for RF and microwave signal routing in test and measurement systems. Operating from 300 kHz to 26.5 GHz, it delivers high isolation performance—up to 100 dB at 9 GHz and 70 dB extending to 54 GHz in SPDT configurations—while maintaining exceptionally low video leakage below 270 mVpp (SPDT) to protect sensitive devices during mixer and amplifier characterization. Microsecond-level switching speed enables rapid test throughput without compromising signal integrity.
