Commercial, Terminated DC-40GHz, Latching, SPDT Coaxial switch

CRT-40

Elite, Terminated DC-40GHz, Latching, SPDT Coaxial switch

The CCRT/CRT-40 is an internally terminated, broadband, SPDT, electromechanical coaxial switch

designed to switch a microwave signal from a common input to either of two outputs. This series switch is

offered with a latching actuator to switch between female K connectors The switches are available in the

frequency range from DC to 40GHz featuring excellent RF and mechanical performance with broadband

operation, high isolation and low insertion loss. The characteristic impedance is 50Ω. Internal terminations

provide an impedance match for the unselected port, making it ideal for applications where port matching

is required.
