Dow-Key Microwave, a subsidiary of Dover Corp., in as ISO 9001 certified manufacturer of electromechanical coaxial and waveguide switches, switch matrices, integrated modular assemblies, and related passive components. Its newest product is the 406HJ-330332-1 high power, break-before-make SPDT Pulse latching switch that addresses insertion loss, weight, and size limitation issues.

This switch features a special input connector that can be mated directly with 50 Ω glass feed-thru, providing direct connection between the switch and the hermetically sealed filter assembly. By mating the switch directly to the filter assembly, RF parameters are improved aver standard solutions with connectorized devices. There is also improvement in weight and space. Designed for space applications, the SPDT Switch exceeded the program requirements in all aspects. The specified bandwidth is specific for the initial application, but the switch can be optimized for other frequency ranges.
