Commercial Latching SPDT, DC-18GHz, Internal 50Ω Termination
Elite Latching SPDT, DC-22GHz, Internal 50Ω Termination
The CCRT-33S/CRT-33S 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.
