Internal Terminations DC-22GHz SPDT Switch
The CRT-33 Switch 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.
The CRT-33 is available with either a failsafe or latching actuator.
