Patent number: 5796317Abstract: A variable impedance coaxial transmission line having a center conductor of constant cross-section, an outer conductor surrounding and coaxial with the center conductor and spaced radially therefrom, and a variable dielectric constant material between the center conductor and the outer conductor. The variable dielectric constant material has a plurality of alternating elements of high dielectric material and low dielectric material arranged along the center conductor from a first end to a second end of the center conductor. The invention also includes a reduced size, high-power broadband power/divider incorporating the variable impedance coaxial transmission line.Type: GrantFiled: February 3, 1997Date of Patent: August 18, 1998Assignee: Tracor Aerospace Electronic Systems, Inc.Inventors: Walter Bohlman, John Greeley

Patent number: 5790003Abstract: A spacer is indicated for a high-frequency coaxial cable with an inner conductor, a tube-shaped outer conductor and a dielectric cavity located between the two conductors which, through the use of different materials, has a higher thermal load capacity in the inner conductor area than in the outer conductor area. When installed, the parts, which are composed of different materials and are superimposed in the radial direction, are mechanically interconnected.Type: GrantFiled: January 22, 1997Date of Patent: August 4, 1998Assignee: Alcatel Alsthom Compagnie Generale d'ElectriciteInventors: Horst Fischer, Hartmut Gohdes

Patent number: 5790002Abstract: A spacer is indicated for a high-frequency coaxial cable with an inner conductor, a tube-shaped outer conductor and a dielectric cavity located between the two conductors, which has a higher thermal load-carrying capacity in the inner conductor area than in the outer conductor area, due to the use of different materials. The parts of the spacer which are made of different materials are radially superimposed and are solidly interlocked with each other by means of injection molding.Type: GrantFiled: January 24, 1997Date of Patent: August 4, 1998Assignee: Alcatel Alsthom Compagnie Generale d'ElectriciteInventors: Horst Fischer, Hartmut Gohdes

Patent number: 5724012Abstract: Transmission-line network of the foam stripline type. To reduce dielectric losses in the foam, part of the foam in the region of the stripline is removed so that the wave properties of the transmission-line network are not impaired. The removed foam forms ducts that may be used for the forced cooling of the stripline using air or other cooling agents.Type: GrantFiled: August 1, 1996Date of Patent: March 3, 1998Assignee: Hollandse Signaalapparaten B.V.Inventor: Petrus Johannus Stephanus Teunisse
