A plurality of intelligent device systems for use with a wideband signal distribution network, and methods for transmitting digital information and receiving digital and non-digital information onto and off of an RF carrier through a wideband signal distribution network, are disclosed. The intelligent device systems provide networks of intelligent devices that modulate and demodulate digital video, IP video/data/voice and digital wireless onto, and off of, a wideband signal distribution system, such as an analog carrier system, using existing EIA/TIA 568 standard wiring infrastructure. The methods modulate and demodulate digital video, IP video/data/voice and digital wireless onto, and off of, a wideband distribution system, such as an analog carrier system, and separate IP portions from non-IP portions.

Intelligent device system and method for distribution of digital signals on a wideband signal distribution system

The present invention uses TEsingle-mode resonators in different orientations that are cascaded along an evanescent mode waveguide. By exploiting multiple orthogonal evanescent modes that can alternatively by-pass, or excite the resonators, cross-coupling between non-adjacent resonators is established and properly controlled. Pseudoelliptic filters are realized without using cumbersome cross-coupled architectures, or reduced spurious performance multi-mode resonators. A 6order filter with two transmission zeros in the lower stopband, a 5order filter with three transmission zeros, and an 8order filter with four transmission zeros are included as embodiments of the present invention.

The intelligent device systems provide networks of intelligent devices that modulate and demodulate digital video, IP video/data/voice and digital wireless onto, and off of, a wideband signal distribution system, such as an analog carrier system, using existing EIA/TTA 568 standard wiring infrastructure. The methods modulate and demodulate digital video, IP video/data/voice and digital wireless onto, and off of, a wideband distribution system, such as an analog carrier system, and separate IP portions from non-IP portions.

A system and method for managing distribution of wideband radio frequency signals includes detecting an impedance signature of a device connected at the end of transmission medium. A switch is opened to apply a wideband radio frequency signal to a transmission medium for distribution. A biasing voltage can be applied to the transmission medium based on the detected impedance signature. A signal conditioning circuit is selected based on the amplitude of the biasing voltage, and the wideband radio frequency signal is distributed to an output device.

A fixed or tunable resonator. The resonator includes an inner conductor, a hollow outer conductor, and a hollow insulating layer. The hollow outer conductor forms a first inner space. The hollow insulating layer is formed from an outer soft dielectric layer, an inner soft dielectric layer, and a ceramic layer disposed between the soft dielectric layers. The hollow insulating layer includes a second inner space formed by the inner soft dielectric layer. The inner conductor is disposed within the second inner space of the hollow insulating layer, and the hollow insulating layer is disposed within the first inner space of the hollow outer conductor.

A filtering system with a probe for coupling two resonators includes an iris having the probe disposed therein coupled between the two resonators. The probe has a transverse opening for receiving a tuning conductor, and the tuning conductor provides adjustable coupling between the two resonators.

A evanescent resonator device includes a short-circuited evanescent waveguide and loading capacitor. The evanescent waveguide of the resonator includes a single length of evanescent transmission line terminated in short circuit, a first support substrate having a predetermined dielectric constant, the first support substrate having a top surface and a bottom surface; a dielectrically loaded feed network including: (a) a second substrate arranged on the top surface of the first support substrate, the second substrate having a predetermined dielectric constant that is higher than the first support substrate; and (b) a metal strip arranged on an upper surface of the second substrate, so that the second substrate is arranged between the first support substrate and the second substrate. A ground plane is arranged on the bottom surface of the first support substrate, the support substrate includes a hollow metalized center area being open on an upper end closest to the second substrate. A ratio of the predetermined dielectric constants of said second substrate to said first support substrate ranges from approximately 2 to 200 so to permit reduced size because of the reduction in required capacitance without a reduction in Q value.

Evanescent resonators

A composite resonator ( ) consisting of a conducting metal ( ) and a dielectric material ( ) is used to provide resonant frequencies lower than can be obtained using the same volume of dielectric alone and with higher unloaded Q than can be obtained using the same volume of metal imbedded into a cavity and used as a resonator. This significantly reduces the cost and size of the resonator ( ) without degrading its performance. An inexpensive metal ( ), such as aluminum, can be substituted for more than half of the dielectric ( ) and stille form a resonator ( ) with substantially equivalent resonant properties. The operative embodiments of the resonator invention ( ) cover composites with doughnut-shaped, i.e., cylindrical, configurations, with the &ldquo;doughnut&rdquo; either metal ( ) or dielectric ( ), and the &ldquo;hole&rdquo; either dielectric ( ) or metal ( ), respectively.
