摘要： An asymmetric, broadband, compact and low-PIM orthomode transducer comprised of two parts is presented. Mating of the two parts results in the formation of a choke flange as well as a critical impedance step which suppresses unwanted modes and enables broadband matching of the junction between the two parts. Furthermore, a cruciform-quatrefoil waveguide type is utilized that transitions to an aperture. This waveguide configuration can lead to a lower overall part length, an improved reflection, and reduced manufacturing costs.

摘要： A flexible and twistable terahertz waveguide assembly has a flexible waveguide with waveguide flange connectors at its ends. The flexible waveguide comprises a segmented tube of a plurality of tube segments which are connected to each other. The tube encloses a dielectric waveguide which is held by means of threads (filaments) at the center of the tube. The individual segments are tiltable and/or pivotable against each other, allowing bending and twisting of the waveguide cable.

摘要： A pedestal connector that incorporates one or more grouped element channel link transmission lines is seen to have a dielectric body and two opposing contact ends that are intended to contact opposing contacts or traces. The dielectric body has an S-shaped configuration such that the transmission lines supported thereon make at least one change in direction, thereby permitting the use of such connector to interconnect elements lying in two different planes. The transmission lines include slots that extend within the frame and which define opposing, conductive surfaces formed on the dielectric body which are separated by an intervening air gap.

The device with a nonradiative dielectric waveguide is, for example, an oscillator, a circulator, a coupler or the like. The device has a pair of parallel conductors, a dielectric strip which is disposed between the conductors and propagates a high-frequency electromagnetic wave in a specified mode, a mounting surface which is formed on one of the conductors, and an end surface which is defined by an end of each of the conductors so as to be vertical to a traveling direction of the electromagnetic wave propagated in the dielectric strip.

摘要： An RF connector includes male and female connector components. The male component has a multi-diameter dielectric housing cylinder with a metal center conductor extending through an opening in the housing. The center pin extends from each end of the dielectric housing. The center pin and the dielectric housing are sized appropriately to provide a matched impedance at microwave frequencies for the use environment to which the male component is connected. The female connector component includes a dielectric body having a center cavity formed therein. A compressible wire bundle forming a compressible conductor member is recessed into the cavity. The compressible conductor protrudes from the far end of the female cavity allowing contact to a mating circuitry. The male connector component is assembled with the female component, the male center pin being brought into electrical contact with the compressible conductor member. The female connector component is not mechanically mounted to the next level of interconnect, but instead the protruding compressible conductor is brought into compressive electrical contact with a mating circuitry on the next interconnect level.
