Abstract:
A passband transversal equalizer comprising:a divider that receives an input signal and splits the input signal along a predetermined number of signal paths; a first plurality of coaxial delay lines coupled to outputs of the divider that delay the signals propagating along the respective signal paths by a first set of nominal relative delays; a plurality of active dividers having push-pull outputs respectively coupled to outputs of each of the coaxial delay lines; an interconnection matrix coupled to each of the active dividers; a plurality of complex weighting and combiner circuit coupled to the interconnection matrix; a second plurality of coaxial delay lines respectively coupled to the complex weighting and combiner circuits that delay the respective signals by a second set of nominal relative delays; and a combiner coupled to the second plurality of coaxial delay lines that combines the signals therefrom to produce an equalized output.
