    Abstract: Methods and systems are provided for multi-chip receivers with loop-through feeds. A receiver that comprises plurality of chips may receive one or more input feeds, with each of the chips generating a corresponding output comprising data (e.g., channels) extracted from the one or more input feeds. Only a first chip may handle reception and/or initial processing of the one or more input feeds, with each one of the remaining chips processing a loop-through feed generated in the first chip, in order to generate the corresponding output of that chip. The loop-through feed may be generated based on the one or more input feeds. In this regard, the loop-through feed may comprise at least one of the one or more input feeds that is partially processed in the first one of the plurality of chips.

    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.

    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.
