PART NUMBER DESCRIPTION
CCR-38S Commercial Normally Open Multi-throw, DC-12 GHz
CR-38S Elite Normally Open Multi-throw, DC-12 GHz
The CCR-38S/CR-38S is a broadband, multi-throw, electromechanical coaxial switch designed to switch
a microwave signal from a common input to any of 7 or 8 outputs. The characteristic impedance is 50
Ohms. The switches are small using the popular connector spacing on a 1.540 dia. circle. Each position
has an individual actuator mechanism allowing random position selection. This also gives the minimum
switching time.
With the normally open actuator, all paths are open when the switch is de-energized.
