  • Publication number: 20160099737
    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: 9160468
    Abstract: A signal receiver chip may be configured to handle a plurality of satellite signals. In this regard, for each received satellite signal the signal receiver chip may determine whether the received satellite signal is unprocessed or partially-processed off-chip; and when the received satellite signal is partially-processed off-chip, at least a portion of processing functions performed in the signal receiver chip may be bypassed. The received satellite signals may then be processed, to generate a corresponding output signals that is configured for communication over a local link. The processing functions bypassed in the signal receiver chip may comprise signal band conversion, particularly down converting from a first band used for over-the-air communication to a second band that is used during handling at receiver side. In this regard, the first band comprises K-band, Ku-band, or Ka-band, whereas the second band comprises L-band, half-L-band, or Extended-L-band.

  • Patent number: 9124925
    Abstract: One or more circuits for use in a transceiver that is collocated with a satellite dish, may receive a satellite signal carrying media content, and remove content protection from the received media content. After removing the first content protection, the one or more circuits may apply second content protection to the media content. The content protection applied by the one or more circuits may adhere to a different protocol, utilize different keys, and/or otherwise be distinguishable from the content protection that was removed. After applying the content protection, the one or more circuits may transmit the media content onto one or more links between the satellite dish and one or more client devices. The removal of the content protection may comprise descrambling and/or decrypting the media content. The application of the content protection may comprise scrambling and/or encrypting the media content.
