The Keysight U9422A is a high-performance FET solid-state SPDT switch engineered for RF and microwave test applications spanning 300 kHz to 26.5 GHz. This switch delivers exceptional isolation—up to 100 dB at 9 GHz and 70 dB at 54 GHz—with video leakage below 270 mVpp, making it ideal for sensitive component measurements and complex switching matrices. Ultra-fast switching speed of less than 450 ns enables dynamic test sequences without compromising signal integrity.
