Waveguide Switches

Overview

Waveguide Switches are designed to route extremely high power signals over a narrow bandwidth at low to high frequencies, making them highly applicable to space applications. To meet this market demand, MPG's Dow-Key expanded its product line and engineering capabilities in 1993, with the acquisition of the Transco Space Qualified Products, augmenting our own industry heritage in Hi-Rel Space programs with an extended line of Waveguide Switching solutions.

Our current technical team, including many of the Transco Space Qualified Products engineers, will help you determine the optimal Waveguide Switch solution or work with your specifications to achieve the a custom design built to your requirements.

Dow-Key Microwave’s full line of Waveguide Switches can be purchased or purpose-built to the following specifications:
