ABSTRACT:
A durable, broad-band low insertion loss RF feedthrough is formed of a straight conductor (5) centrally supported by, hermetically sealed to and axially extending through the center of a strong, rigid, impervious ceramic disk (3). The ceramic disk is hermetically sealed, directly or indirectly, to the metal barrier (11) through which the feedthrough is to propagate RF energy. The new ferrule and ferrule-less ceramic metal RF feedthroughs avoid the use of glass, conventional in existing feedthroughs. The novel feedthrough serves as the principal element of a microwave microstrip line to waveguide transition.
