A "plug-and-go" switching solution from Dow-Key leverages a selection of control boards, harnesses, and CANbus electromagnetic switches through 40 GHz to form customized switch matrices. A choice of various switch configurations from single-pole, three-throw (SP3T) through single-pole, 12-throw (SP12T) switches are available with frequency range of DC to 18 GHz, DC to 26.5 GHz, and DC to 40 GHz with RF-11 harnesses and Ethernet or GPIB switching remote control boards. The components can be readily combined to form a switch-matrix solution with the required frequency range and switching performance.
