  • Method and device for frequency translation in powerline communications
    Patent number: 6985715
    Abstract: A method and apparatus for transmitting and receiving RF signals for broadband communications using power lines as communication medium. A super-heterodyne structure is used to translate the signals from one frequency to another so as to avoid interference sources, which may corrupt the communication signals. In the heterodyne structure, a plurality of local oscillators are used to mix the local oscillator signals with the communication signals for frequency translation. A plurality of frequency filters are used to filtered out unwanted signals. The communication signals are imparted onto or received from the power lines via couplers operatively connected to modems.
