    Abstract: A wideband receiver system comprises a wideband analog-to-digital converter (ADC) module and a digital frontend (DFE) module. The wideband ADC is configured to concurrently digitize a band of frequencies comprising a plurality of desired channels and a plurality of undesired channels. The DFE module is coupled to the digital in-phase and quadrature signals. The DFE module is configured to select the plurality of desired channels from the digitized band of frequencies, and generate an intermediate frequency (IF) signal comprising the selected plurality of desired channels and having a bandwidth that is less than a bandwidth of the band of frequencies, where the generation comprises frequency shifting of the selected plurality of desired channels. The IF signal may be a digital signal and the DFE is configured to output the IF signal via a serial or parallel interface.

    Abstract: A wideband receiver system is provided to concurrently receive multiple RF channels including a number of desired channels that are located in non-contiguous portions of a radio frequency spectrum and to group the number of desired channels into a contiguous frequency band. The system includes a wideband receiver having a complex mixer for down-shifting the multiple RF channels and transforming them to an in-phase signal and a quadrature signal in the baseband. The system further includes a wideband analog-to-digital converter module that digitizes the in-phase and quadrature signals and a digital frontend module that transforms the digital in-phase and quadrature signals to baseband signals that contains only the number of desired RF channels that are now located in a contiguous frequency band. An up-converter module up-shifts the baseband signals to a contiguous band in an IF spectrum so that the system can directly interface with commercially available demodulators.

    Abstract: A monolithic integrated circuit for use in a microwave backhaul system may comprise a plurality of microwave transceivers and outdoor-unit to indoor-unit (ODU/IDU) interface circuitry. The monolithic integrated circuit may be configurable into an all-outdoor configuration in which the ODU/IDU interface circuitry is disabled. The monolithic integrated circuit may be configurable into a split-indoor-and-outdoor configuration in which the ODU/IDU interface circuitry is enabled to communicate signals between an outdoor unit of the microwave backhaul system and an indoor unit of the microwave backhaul system. While the monolithic integrated circuit is configured in the split-indoor-and-outdoor configuration, the ODU/IDU interface circuitry may be configurable to operate in at least a non-stacking mode and a stacking mode.

    Abstract: Methods and systems for interference avoidance in a multi-protocol communication system may comprise receiving signals in a first communications protocol in a first frequency range and preventing interference signals from being generated in said first frequency range by configuring channel usage in a second communications protocol in a second frequency range based on said received signals. The configuring channel usage may include avoiding communicating in taboo channels and the received signals in said first communications protocol and signals in said configured channels in said second communications protocol may be communicated over one or more coaxial cables based on the configured channel usage. The taboo channels may be selected based on said received signals such that interference signals from said second frequency range do not occur in said first frequency range. The first frequency range comprises a cable or satellite television frequency range, or data over cable service interface standard (DOCSIS).

    Abstract: A microwave backhaul system may comprise a monolithic integrated circuit comprising an on-chip transceiver, digital baseband processing circuitry, and auxiliary interface circuitry. The on-chip transceiver may process a microwave signal from an antenna element to generate a first pair of quadrature baseband signals and convey the first pair of phase-quadrature baseband signals to the digital baseband processing circuitry. The auxiliary interface circuitry may receive one or more auxiliary signals from a source that is external to the monolithic integrated circuit and convey the one or more auxiliary signals to the digital baseband processing circuitry. The digital baseband processing circuitry may be operable to process signals to generate one or more second pairs of phase-quadrature digital baseband signals.
