Commercial Normally Open Multi-throw, DC-18GHz
Elite Normally Open Multi-throw, DC-22GHz
The CCT-38S/CT-38S is an internally terminated, broadband, multi-throw, electromechanical coaxial
switch designed to switch a microwave signal from a common input to any of 3, 4, 5, or 6 outputs.
The characteristic impedance is 50 Ohms. Internal terminations provide an impedance match for the
unselected ports. The switches are small using the popular connector spacing on a 1.062” dia. circle.
Each position has an individual actuator mechanism allowing random position selection. This also
minimizes switching time.
The CCT-38S/CT-38S comes with a normally open actuator. For the normally open actuator, all ports are
terminated in 50 Ohms, except the common input port which is open when the switch is de-energized.
