The SMC-061D200 from Scientific Microwave Corporation is a Double-Ridge Waveguide Pressure Window (Kapton) that operates from 2 to 4.8 GHz. It has a pressure rating of 30 psi and uses a Kapton film seal. This pressure window can improve the power handling of waveguide systems by maintaining high pressure inside a chain of cascaded components. It has a WRD200 waveguide interface and can operate at high pressure, with an exceptional matching level.
