  • LNB control circuit that provides power and control commands
    Patent number: 8756647
    Abstract: One embodiment may take the form of a control circuit that provides a combined power signal and control signal to an LNB of a satellite system. The control circuit output may be transmitted to an LNB by a set-top box (STB) such that the STB may control the LNB. The control circuit may accept an enable signal from the STB to alter the circuit from a transmitting circuit to a receiving circuit. The control circuit may also integrate the functionality of a low pass filter into the communication signal circuit, thereby removing the need for a low pass filter at a power supply output. The control circuit may also provide a low overall power consumption of the circuit by isolating the communication signal from the power supply signal before the signals are combined.
