A method includes tapping power from a broadband RF input, filtering the tapped power with a plurality of band pass filters, measuring the power filtered by each of the plurality of band pass filters and controlling an adaptive equalizer circuit to flatten excessive non-linear frequency response from the broadband RF input as a function of measured power filtered at each of the plurality of band pass filters. An apparatus, includes a broadband RF input, a plurality of band pass filters coupled to the broadband RF input, at least one power measurement circuit coupled to the plurality of band pass filters and an adaptive equalizer circuit coupled to the at least one power measurement circuit and the plurality of band pass filters, wherein the at least one power measurement circuit provides control signals to the adaptive equalizer circuit as a function of measured power at each of the plurality of band pass files and wherein the adaptive equalizer circuit flattens excessive non-linear frequency response of the broadband RF input. |
