Abstract

A bi-directional RF signal amplifier includes a housing with an RF input port. A power divider network within the housing terminates to a plurality of active RF output ports. An active communications path connects the RF input port to the power divider network. A passive communications path connects the RF input port to a passive RF output port. A MoCA input/output port is provided on the housing. A MoCA signal path connects the power divider network to the MoCA input/output port, and a MoCA pass filter is located along the MoCA signal path. In another embodiment, a passive splitter includes a housing with an RF input port, a power divider network, and a plurality of CATV/MoCA RF output ports. A CATV communications path connects the RF input port to the power divider network. A MoCA input/output port is provided on the housing. A MoCA signal path connects the power divider network to the MoCA input/output port, and a MoCA pass filter is located along the MoCA signal path.
