ABSTRACT:
A coaxial fitting comprises, a metallic tubular ferrule having a forward portion with knurling thereon and a rearward portion with external threads thereon by which such fitting is coupleable to a coaxial cable, the fitting also comprising an inner metallic rod conductor extending in the ferrule in concentric radially spaced relation therewith, and a dielectric plug disposed in the ferrule radially in contact with the ferrule and inner conductor to maintain them in fixed relation, the plug being longitudinally in contact with an inwardly projecting internal annular shoulder in the ferrule. The knurled portion of the fitting is adapted to be press fitted into a bore formed in the housing of a microwave device to provide a port for microwaves supplied to or from such device. The metallic parts of the fitting interiorly comprise copper and have precious metal platings thereon to reduce microwave resistance losses.
