Abstract:
RF signal amplifiers for cable television networks are provided that include an RF input port. a power amplifier coupled to the RF input port and a power divider having an input that is coupled to an output of the power amplifier. The power divider includes a first directional coupler that is coupled to an output of the power amplifier. The directional coupler includes a first output branch and a second output branch. A first bypass circuit is coupled between the first and second output branches of the first directional coupler. A response of the power divider includes a null that substantially blocks signals received at the input of the power divider from passing to outputs of the power divider in a subset of frequencies within the range of 5 MHz to 1550 MHz. These RF signal amplifiers may provide improved performance, robustness and reliability when used in MOCA networks.
