A NEW FAMILY OF ELECTROMECHANICAL SWITCHES FOR A SINGLE-SLOT VXI CHASSIS

Ventura, California – October, 2003

Dow-Key Microwave (a subsidiary of Dover Corp., NYSE:DOV), is an ISO 9001 certified manufacturer of electromechanical coaxial and waveguide switches, Switch Matrices, Integrated Modular Assemblies, and related passive components. Its’ newest product is a family of VXI Switches with SMA connectors offering three basic configurations: SP6T, Double SPDT, and a Transfer Switch. DC characteristics include 20-28 VDC (24 VDC nominal) operation voltage. Equipped with a failsafe actuator, these devices switch in 20 ms (max).

All three switches have the same control connector, but each model has its own unique pin-out that plugs into the universal control circuitry. The control circuitry instantly recognizes the pin-out of the inserted switch and reconfigures the control interface accordingly. These VXI Switches are designed with an emphasis on reliability, extended operating life, and phase and insertion loss repeatability. The contacts’ geometry, materials, mechanical finishes, and plating schemes are carefully selected to provide the product with an operating life well exceeding 2 million cycles.
