  • Microwave connector
    Patent number: 7168979
    Abstract: A coaxial connector including an outer conductor, a glass to metal seal (GMS) assembly, and a center conductor, is disclosed. The outer conductor has a tubular shape and defines longitudinal axis. Here, the center conductor and the GMS assembly are coupled before they are placed within the outer conductor. When the GMS assembly is coaxially placed within the outer conductor, the GMS assembly and the outer conductor define a variable gap enclosure. Fusing agent such as solder is placed within the variable gap enclosure. A bead is inserted into the outer conductor surrounding the center conductor and engaging the center conductor at a circumferential slot. The slide-on dielectric bead provides support for the center conductor and maintains the center conductor's position within the outer conductor and its characteristic impedance throughout.

  • Asymmetric support for high frequency transmission lines
    Patent number: 6765461
    Abstract: Asymmetric support for high frequency transmission lines. An asymmetrical support structure coaxially supports a center conductor over a ground plane using a dielectric material. Absorbing material between the dielectric and the outer conductor reduces the effects of high order modes.
