The Agilent/Keysight 33334C is a solid-state RF switch engineered for signal routing and automation in precision test systems. Operating from DC to 26.5 GHz, it delivers the frequency coverage demanded by broadband RF and microwave applications. The switch leverages permanent magnet latching to maintain position after activation, eliminating the need for continuous control power. Controlled wiping action at RF contacts removes debris and sustains repeatability across millions of operating cycles.
