  • High Power Switches

    Dow-Key Microwave

    MPG Switch line of High Power RF & Microwave Switches fit applications where electromechanical switches fail to meet the size, cost and speed of project specifications. At microwave frequencies, a high power switch acts as a current-controlled resistor, allowing current to flow in a single direction. When forward biased, the switch relay behaves as a closed circuit, but when the current is reverse biased, the RF switch becomes an open circuit.

  • Waveguide

    Dow-Key Microwave

    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.

  • Coaxial Switches

    Dow-Key Microwave

    Dow-Key Coaxial RF switches are employed in RF testing equipment and large RF communication systems and networks to efficiently route microwave signals or RF energy within a transmission line. Our Coaxial RF switches route RF signals over a broad bandwidth from DC to 40 GHz, and are now offered with a Low PIM option to improve passive intermodulation levels from -110dBc (standard switch) to -160dBc.

  • High Repeatability Switches

    Dow-Key Microwave

    High Repeatability Switches are designed to stand up to rigorous requirements over an extended lifecycle. Dow-Key Microwave’s Reliant line of High Repeatability Switches meets these basic requirements with a dependable and economical switching solution, backed by decades of design and manufacturing innovation.
