  • Patent number: 10396850
    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.

  • Patent number: 10230424
    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.

  • Publication number: 20160261298
    Abstract: Receiver architectures and methods of processing harmonic rich input signals employing harmonic suppression mixers are disclosed herein. The disclosed receivers, mixers, and methods enable a receiver to achieve the advantages of switching mixers while greatly reducing the mixer response to the undesired harmonics. A harmonic mixer can include a plurality of mixers coupled to an input signal. A plurality of phases of a local oscillator signal can be generated from a single local oscillator output. Each of the phases can be used to drive an input of one of the mixers. The mixer outputs can be combined to generate a frequency converted output that has harmonic rejection.

  • Patent number: 9320019
    Abstract: A WiFi device, which utilizes full spectrum capture, captures signals over a wide spectrum including one or more WiFi frequency bands and extracts one or more WiFi channels from the captured signals. The AP analyzes the extracted WiFi channels and aggregates a plurality of blocks of WiFi channels to create one or more aggregated WiFi channels based on the analysis. The WiFi frequency bands comprise 2.4 GHz and 5 GHz WiFi frequency bands. The AP determines one or more characteristics of the extracted WiFi channels based on the analysis. The determined characteristics comprise noise, interference, fading and blocker information. The AP generates a channel map comprising at least the extracted one or more WiFi channels based on the determined characteristics. The AP dynamically and/or adaptively senses the extracted one or more WiFi channels and updates the determined characteristics of the extracted WiFi channels.
