Abstract
A wideband high frequency signal splitter device utilized in a signal distribution network is disclosed. An input signal having a substantially extended frequency bandwidth is applied to an input port of the proposed signal splitter from the upstream portion of a signal distribution network. Within the signal splitter the signal is suitably divided into its constituent components. The constituent components include a low frequency component, a high frequency component and an AC current power component. The components are divided separately and re-routed to combiner units associated with suitable output ports. The separate components are combined and fed through the output ports to the downstream portion of the signal distribution network. The signal splitter device is also functional as a signal combiner device by combining separate signals received from the downstream portion of the network via the output ports and transmitting the combined signals to the upstream portion of the signal distribution network.
