Abstract
An optical low-noise block down-converter for a satellite television system is disclosed. The optical low-noise block down-converter includes a first down-conversion module coupled to a satellite antenna of the satellite television system for converting a vertically polarized signal received by the satellite antenna into a first intermediate frequency signal, a second down-conversion module coupled to the satellite antenna for converting a horizontally polarized signal received by the satellite antenna into a second intermediate frequency signal, and a third down-conversion module having a first input terminal coupled between the satellite antenna and a first down-converter of the first down-conversion module and a second input terminal coupled between the satellite antenna and a second down-converter of the second down-conversion module for draining out part of the vertically polarized signal and the horizontally polarized signal to combine and convert into a legacy electrical signal.
