RF And Microwave Coaxial Switches
For over 65 years, Dow-Key Microwave has been a trusted supplier of RF and microwave coaxial switches for commercial, military, avionics, space, test, and other applications. Designed and manufactured in the U.S., these switches are available in SPDT, DPDT, and multi-position configurations, and feature low insertion loss / high isolation performance, excellent repeatability, and long lifespans.
Dow-Key Microwave has supplied high-performance RF and microwave coaxial switches to engineers in the commercial and defense industries since 1945. These bidirectional electromechanical switches are available in SPDT (single pole, double throw), DPDT (double pole, double throw), and multi-position (up to SP14T) configurations and cover a broad range of frequencies, RF power levels, and passive intermodulation (PIM) levels. They boast low insertion loss / high isolation, excellent repeatability, and a long lifespan and are available with a variety of connector types, terminated and non-terminated ports, and ruggedized and non-ruggedized packages. All Dow-Key coaxial switches are designed, assembled, and tested in the United States, at the company’s Ventura, CA, facility.
Applications
Dow-Key coaxial switches are integrated into RF and microwave systems across a wide range of industries including:
- Military (electronic warfare, radar, etc.)
- Avionics (antennas, radar, communications, etc.)
- Space (satellite/SATCOM, launch vehicles, manned vehicles, etc.)
- Automated test equipment (ATE)
- Wireless telecommunications
- Semiconductor manufacturing
Dow-Key’s experienced engineering team can also work with you to design and manufacture a custom coaxial switch or integrated switching system to meet your specific performance, design/integration, control, testing, cost, and delivery time requirements.
Benefits & Features
-
Dow-Key’s coaxial switches meet your system’s demanding performance requirements through their:
- Broad operating frequency range (up to 40 GHz)
- Low VSWR (as low as 1.10 maximum)
- Low insertion loss (as low as .10 dB maximum)
- High isolation (as high as 85 dB minimum)
- High power (up to 5000 W)
- Low PIM levels (down to-160 dBc)
- Minimize repair and replacement costs, thanks to the switches’ excellent reliability and repeatability over a long lifespan (1 million life cycles or 5 million life cycles minimum), and Dow-Key’s distinguished heritage of performance (as the oldest RF/microwave switch manufacturer in the U.S., founded in 1945).
- Reduce your design footprint or satisfy limited space requirements with available compact versions of the switches.
- Shorten time to market and meet Department of Defense (DoD) requirements by working with a U.S.-based manufacturer.
- Leverage Dow-Key’s technical know-how, with unlimited technical support before and after purchase.
