Waveguide Plasma Switch

Jones Microwave’s waveguide plasma switch is a light-activated, solid-state RF switching technology that delivers electromechanical-class performance with solid-state speed, reliability, and scalability from microwave to sub-THz frequencies.

The platform enables low-loss, high-power, and high-isolation switching within waveguide structures in a robust solid-state form factor, designed for integration into advanced RF systems. Our design with DC control (TTL) enables flexible optical interfacing while maintaining complete isolation from the RF path.

Key Capabilities

  • Controllable attenuation and
    reflective-to-absorptive operation

  • Solid-state switching with no moving parts for enhanced reliability

  • Wideband operation within standard waveguide bands up to sub-THz

  • Flexible optical control via integrated or remote light source with DC interface

  • High-power handling with reduced footprint vs electromechanical solutions
