Founded in 1945, MPG Solutions flagship Switch brand Dow-Key remains the world’s largest manufacturer of electromechanical RF Switches, including our durable and reliable line of Coax Switches (Coaxial Switches). Designed to reliably route microwave signals or RF energy from point to point within a transmission line, Dow-Key Microwave’s Coax Switches are equally at home in an industrial environment, such as large RF communication systems and networks, or within the lab supporting RF testing equipment.
Our technical team and experienced engineers will help you determine the optimal Coaxial Switch or Coax Relay solution for your needs from our extended line of off-the-shelf and custom-designed products.

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.

High Repeatability Switches are designed to stand up to rigorous requirements over an extended lifecycle. Our 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.
Reliant High Repeatability Switches can operate at temperatures below 25°C, up to 15,000 feet in altitude, and can also be stored up to 50,000 feet without performance degradation. Control can be instituted by applying ground to close the desired port, via TTL logic (by applying +5vdc to close a port or +0Vdc to open a port) or CANbus (to use with controller boards).
At MPG, we help customers meet specifications where insertion loss repeatability and switch life are critical, with an economically priced High Repeatability Switch that can be purpose-built to the following specifications:
