发明名称 INTEGRATED MULTI-SAT LNB AND FREQUENCY TRANSLATION MODULE
摘要 Systems and devices for receiving satellite signals are disclosed. A system in accordance with the present invention comprises a plurality of amplifiers, each amplifier in the plurality of amplifiers receiving the signals, a Frequency Translation Module, comprising a plurality of analog-to-digital converters, wherein each amplifier in the plurality of amplifiers is coupled to a separate analog-to-digital converter in the plurality of analog-to-digital converters, wherein the plurality of analog-to-digital converters convert the signals into digital data streams, a digital signal processing section, coupled to the plurality of analog-to-digital converters, wherein the digital signal processing section at least translates the frequency of the digital data streams and filters the digital data streams, a digital-to-analog section, coupled to the digital signal processing section; wherein the digital-to-analog section downconverts the satellite signals to an intermediate frequency band, and a receiver, coupled to the digital-to-analog section, wherein the receiver receives an output of the digital-to-analog section of the module at the intermediate frequency band, the output of the digital to analog section being on a single coaxial cable.
