Hermetically sealed electromagnetic window and method of forming the same

摘要

A hermetically sealed electromagnetic window is formed by butt end brazing an overhanging dielectric window between first and second waveguide segments. The waveguide segments have opposed knife edges with a dielectric insert positioned between the knife edges. A pair of brazing forms are inserted between the insert and the two knife edges. The window is heated, causing the brazing material to reflow and provide a hermetic seal between the insert and the waveguide segments, and a conductive path between the waveguide segments.
