According to one exemplary embodiment, a front-end system for processing a composite wideband signal comprises a pre-receiving unit including a multiplexer for separating the composite wideband signal into a plurality of filtered signals. The front-end system further comprises a plurality of discrete frequency band outputs corresponding to the plurality of filtered signals, and a tuner/down-converter coupled to at least one of the plurality of discrete frequency band outputs. In one embodiment, the pre-receiving unit of the front-end system further comprises a second multiplexer for separating at least one of the plurality of filtered signals into a second plurality of filtered signals. In one embodiment, the pre-receiving unit may further comprise a low noise amplifier for processing at least one of the plurality of filtered signals before it is input to the second multiplexer.
