RF & Microwave Solid State Switches

Keysight’s solid state switches provide superior performance with high isolation and fast switching speed across a broad operating frequency range. Keysight’s FET switches provide safe, accurate test for sensitive RFIC components. Keysight PIN diode switches provide ultra-fast, accurate test in automate test equipment (ATE systems).

Applications include instrumentation, communications, radar, antenna and many other test systems that require high speed RF and microwave switching. The long operating life of solid state switches makes them an ideal choice in large-scale manufacturing environments.

Understanding RF/Microwave Solid State Switches and Their Applications: learn about the different types of solid state switches, the technologies used to design them, and the important parameters to consider when selecting a solid state switch. Application Note
