Configurable, highly-integrated satellite receiver
View Patent ↗A direct broadcast satellite (DBS) reception assembly may comprise an integrated circuit that is configurable between or among a plurality of configurations based on content requested by client devices served by the DBS reception assembly. In a first configuration, multiple satellite frequency bands may be digitized by the integrated circuit as a single wideband signal. In a second configuration, the satellite frequency bands may be digitized by the integrated circuit as a plurality of separate narrowband signals. The integrated circuit may comprise a plurality of receive paths, each of the receive chains comprising a respective one of a plurality of low noise amplifiers and a plurality of analog-to-digital converters.
1. A system comprising:
an integrated circuit for use in a direct broadcast satellite (DBS) and/or Fixed Satellite Service (FSS) reception assembly, the integrated circuit residing on a single silicon die and comprising a receive chain including a mixer, a filter, and an analog-to-digital converter (ADC), wherein:
in a first configuration of said integrated circuit, said mixer and said filter are configured to direct downconvert a first narrow satellite frequency band for digitization by said ADC;
in a second configuration of said integrated circuit, said mixer and said filter are configured to direct downconvert a second narrow satellite frequency band for digitization by said ADC;
in a third configuration of said integrated circuit, said mixer and said filter are configured to direct downconvert said first narrow satellite frequency band and said second narrow satellite frequency band as a single wideband signal for digitization by said ADC; and
configuration among said first configuration, said second configuration, and said third configuration is controlled by a control signal generated by control logic of said integrated circuit based on content requested by client devices served by said DBS reception assembly.
2. The system of claim 1 , wherein said first narrow satellite frequency band and second narrow satellite frequency band comprise a low band and a high band in the X-band and/or Ku-band.
3. The system of claim 2 , wherein:
said low band is from approximately 10.7 GHz to approximately 11.7 GHz; and
said high band is from approximately 11.7 GHz to approximately 12.75 GHz.
4. The system of claim 1 , wherein said first narrow satellite frequency band and said second narrow satellite frequency band are in the Ka-band.
5. The system of claim 4 , wherein said first narrow satellite frequency band and second narrow satellite frequency band satellite bands comprise two or more of:
a band from approximately 17.3 GHz to approximately 18.8 GHz;
a band from approximately 18.3 GHz to approximately 18.8 GHz; and
a band from approximately 19.7 GHz to approximately 20.2 GHz.
6. The system of claim 1 , wherein:
in said first configuration of said integrated circuit, an input of said receive chain is an output of a single off-chip low noise amplifier;
in said second configuration of said integrated circuit, said input of said receive chain is an output of a single off-chip low noise amplifier; and
in said third configuration of said integrated circuit, said input of said receive chain is a combined output of a plurality of off-chip low noise amplifiers arranged in parallel.
