RF Microwave Vacuum Window (Altair Technologies, Inc.)

RF Windows manufactured by Altair transmit RF or microwave power from a vacuum into an air filled or more likely an inert gas filled transmission line like a waveguide. It is a resonant cavity designed to maximize RF power transmission, with minimal loss over a desired frequency range. RF Windows are used on Linear Accelerators, Klystrons, Traveling Wave Tubes and other electron beam devices or RF systems that use microwave energy.
