Waveguide Switches (Hi-Rel)
In 1993 Dow-Key expanded its involvement in Hi-Rel space programs with the acquisition of the Transco Space Qualified Products. In addition to the heritage for the Hi-Rel waveguide switches, many of the Transco design engineers stayed with Dow-Key and are still employed with us today. The Dow-Key waveguide switches were included in high profile space missions such as the Parker Solar Probe, and most recently the Nancy Grace Roman Space Telescope.
The below table shows some examples of space-qualified Waveguide switches that were recently manufactured at Dow-Key Microwave:
