CRT-53S

Elite Failsafe SPDT, DC-26.5GHz, Internal 50Ω Termination

The CCRT-53S/CRT-53S is an internally terminated, broadband, SPDT, electromechanical coaxial switch

designed to switch a microwave signal from a common input to either of two outputs. The characteristic

impedance is 50 Ohms. Internal terminations provide an impedance match for the unselected port. The

switches are small with the minimum spacing that is compatible with SMA connectors.
