High Power DC-8GHz Multi - Throw Switch
SP7T and SP8T versions only
The CS-18 Switch is a broadband multi-position coaxial switch designed to switch RF signals
from one input port to any one of 3 through 8 output ports. It is readily adapted to any 50 Ohms
transmission line system. The standard actuator gives individual solenoid control of each
position and when de-energized, all positions are open. Standard actuator voltage is 28 VDC.
The primary advantage of this switch over the miniature versions shown on previous pages
is the higher power handling capability.
