  • Apparatus, system and method for improved calibration and measurement of differential devices
    Patent number: 6997753
    Abstract: An apparatus, system and method for facilitating the calibration and measurement of differential devices by a variety of laboratory fixtures. An adapter is used to transition the connection of standard coaxial interfaces to a hermaphroditic differential interface while compensating for discontinuities on impedance at the connection. The adapter includes a transition region with conductors and shield dimensions that compensate for the discontinuity in impedance. The adapter has pin and socket inputs so that a mated pair of the adapters provides an insertable device for test and measurement on a four port vector network analyzer.

  • Dielectric waveguide having higher order mode suppression
    Patent number: 4875026
    Abstract: A dielectric waveguide for the transmission of electromagnetic waves is provided comprising a core of polytetrafluoroethylene (PTFE), one or more layers of PTFE cladding overwrapped around the core, a mode suppression layer of an electromagnetically lossy material covering the cladding and an electromagnetic shielding layer covering the mode suppression layer. The mode suppression layer is preferably a tape of carbon-filled PTFE. Another electromagnetically lossy material layer may be placed around the shield to absorb any extraneous energy.

  • Dielectric waveguide having higher order mode suppression filters
    Patent number: 4792774
    Abstract: A dielectric waveguide for the transmission of electromagnetic waves is provided comprising a core of polytetrafluoroethylene (PTFE), one or more layers of PTFE cladding overwrapped around the core, the core and/or cladding having mode suppression filters of an electromagnetically glossy material embedded therein, and an electromagnetic shielding layer covering the cladding. The mode suppression filters are preferably mica cards.

  • Dielectric waveguide delay line
    Patent number: 4785268
    Abstract: A delay line is provided for effecting a desired delay in the transmission of electromagnetic waves in the microwave and millimeter range of the spectrum. The line comprises a length L of a dielectric waveguide for transmission of electromagnetic waves comprising a core of polytetrafluoroethylene having one or more layers of polytetrafluoroethylene overwrapped around the core, wherein T=KL/c, in which T is the total time delay , c is the velocity of light in free space and K is the delay constant of the dielectric waveguide. Preferably, the delay line is overwrapped around a mandrel.
