Series CCT-38S/CT-38S Multi-Throw DC18 GHz/DC-22 GHz COAX SWITCHES Normally Open Coaxial Switch PART NUMBER DESCRIPTION CCT-38S Commercial Normally Open Multi-throw, DC-18GHz CT-38S 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.
