The Agilent/Keysight U9397C is a high-performance FET solid-state SPDT switch engineered for RF and microwave test applications spanning 300 kHz to 18 GHz. This component delivers exceptional signal routing capability with insertion loss below 5.0 dB, isolation exceeding 90 dB, and settling times near 500 µs—critical for precision measurements in instrumentation, communications, and radar systems. The integrated TTL/CMOS driver and single DC bias voltage simplify integration while maintaining low video leakage below 10 mVpp to protect sensitive devices during switching events.
