Window material
Waveguide Pressure Windows is used to prevent waveguide system from moisture, dirt and dust or to isolate waveguide pressure from non-pressurized required system, which belongs to a kind of seal components. It can pass signal but isolate others useless sections. The power-handling capacity of a waveguide based system can be increased with this components.
