Voltage reference conductors carrying the same voltage level are coupled together at one or more points between the ends of the connector to shift the connector's resonant frequency beyond an operating frequency range of the data signals. Decoupling capacitors may alternatively or additionally be inserted between pairs of voltage reference conductors carrying high and low voltage levels at one or more points between the ends of the connector to shift the connector's resonant frequency beyond an operating frequency range of the data signals.

  • Patent number: 7692125
    Abstract: An apparatus includes a radome and an evanescent wave-coupled windowing system in the radome. In operation, the apparatus receives radiation reflected from an object that is incident upon a windowing system; emits evanescent waves from the windowing system whose amplitudes are proportional to the angle of incidence of the radiation; and non-coherent, Fresnel direction finds the object.

  • Publication number: 20100007431
    Abstract: A signal transmission structure includes two power planes, a signal line and a first pillar. The power planes spaced by an interval space provide a first voltage and a second voltage respectively. The signal line, disposed on first surfaces of the power planes, is disposed across the interval space. The first pillar is disposed within the interval space and is aside the signal line, in which the first pillar is apart from the power planes and the signal line.

  • Patent number: 7606592
    Abstract: The design and use of a simplified, highly efficient, waveguide-based wireless distribution system are provided. A low-loss waveguide is used to transport wireless signals from a signal source or sources to one or more receiver locations. One or more adjustable signal coupling devices partially insert into the waveguide at predetermined locations along the length of the system to provide variable, controlled extraction of one or more wireless signals. Low-loss impedance matching circuitry is provided between the waveguide coupling devices and output connectors to maintain high system efficiency. The system offers the capability of supplying signals of high strength and high quality to a large number of receivers in a wide wireless coverage area via a plurality of signal radiators. Some embodiments of the system are readily adaptable for wireless distribution service in HVAC plenum spaces. A system that combines the functions of fire extinguishing and waveguide wireless distribution is also disclosed.

  • Patent number: 7557679
    Abstract: A feedthrough for feeding a microwave signal through a wall of a casing comprises a signal waveguide having at least two portions having different cross-sections. The portion having the smaller cross-section is filled with plastically-deformable dielectric material which, under the action of pressure and heat, is bonded to the walls of the portion in which it is located. The dimensions of the portion are such as to provide an impedance match with the adjacent portions. An antenna couples electromagnetic energy between the waveguide and a strip transmission line. A metal cap seals the end of the waveguide and screens the antenna.

  • Patent number: 7538633
    Abstract: One embodiment of the present invention provides a system which drives on-chip wires using capacitive coupling. During operation, the system drives a signal onto a driven wire. This signal feeds from the driven wire through a coupling capacitor onto a coupled wire, which is an on-chip wire that routes the signal to its destination. Feeding the signal through the coupling capacitor reduces the voltage swing of the corresponding coupled signal on the coupled wire, thereby lessening the power required to drive the coupled signal on the coupled wire.

  • Publication number: 20090102582
    Abstract: At microwave frequencies, the use of transmission lines as a design element becomes interesting due to the small wavelengths. Inductors as part of an on-chip resonator can be made with a shorted stub, which is a transmission line, shorted at the end. Placing a MIM-capacitor at the beginning of the shorted stub can make a resonator. Shielding this kind of resonator by means of vias or stacked vias enables very compact filter designs.
