Multi-Throw Internal Terminations DC-22GHz
The CT-39 Switch is a 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 impedence 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 CT-39 comes with a latching actuator. The latching switch
remains in the last position selected when the switch is de-energized.
STD dual command requires a reset pulse before a new selected
position. A separate reset circuit allows all positions to be set to an
open position. User must provide both reset (clear) and set (select
new position) commands.
