Agilent/Keysight U9422B

The Keysight U9422B is a GaAs FET solid-state switch engineered for RF and microwave signal routing from 300 kHz to 50 GHz. This single-pole, double-throw (SPDT) device delivers isolation exceeding 60 dB at 50 GHz, with performance reaching 100 dB at 9 GHz and 70 dB up to 54 GHz. Video leakage is held below 270 mVpp, protecting sensitive measurement chains. Switching transitions occur in microseconds, enabling rapid test sequencing across broadband applications.

The hermetically sealed, compact housing integrates USB control via Soft Front Panel software or SCPI command programming through Keysight IO. Optional multiport configuration connectivity supports PXIe and USB VNA platforms without external adapters. Connector options span solder terminals and USB Type-C interfaces, with lengths of 1 or 2 meters available.
