DESCRIPTION
CCRT-53S
Commercial Failsafe SPDT, DC-26.5GHz, Internal 50Ω Termination
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.
