1. A RF signal amplifier for a cable television network, comprising:

  • an RF input port;

    a power amplifier coupled to the RF input port;

    a power divider having an input that is coupled to an output of the power amplifier and first and second outputs, the power divider comprisinga first directional coupler that has a first output branch and a second output branch; and

    a first bypass circuit coupled between the first and second output branches of the first directional coupler,wherein a response of the power divider includes a null that substantially blocks signals received at the input of the power divider from passing to the first or second outputs of the power divider in a subset of frequencies within the range of 5 MHz to 1550 MHz.
