The Keysight U9422C is a solid-state FET switch in Single Pole Double Throw (SPDT) configuration, engineered for high-performance RF and microwave signal routing across 300 kHz to 54 GHz. Built for precision test and measurement environments, it delivers isolation up to 100 dB at 9 GHz and maintains 70 dB isolation to 54 GHz, with video leakage below 50 mVpp. The device features USB control for seamless integration into PXIe and USB VNA systems, 1.85 mm connectors for wideband operation, and microsecond-level switching speed. Its compact form factor (64.5 × 67.7 × 23 mm for standard configuration) makes it suitable for dense switch matrices and instrumentation racks. The U9422C is rated for operation to 4,600 meters altitude and 95% relative humidity (non-condensing), with documented shock and vibration survival specifications across end-use and transportation environments.
