Front end multiplexer topology for a set top box

An apparatus and method for processing satellite signals is provided. A switch (116) receives an input signal having a predetermined frequency range, the predetermined frequency range including at least two frequency sub-bands. A first diplexer (110) is connected to a first output of the switch (116) and generates a first filtered signal including a first frequency sub-band and a second frequency sub-band and a second filtered signal including a third frequency sub-band. A second diplexer (104) is connected to a second output of the switch (116) and generates a third filtered signal including the first frequency sub-band and a fourth filtered signal including the second frequency sub-band. A controller (602) activates the switch (116) to operate between a first mode and a second mode. In the first mode, the switch (116) provides the input signal to the first diplexer (110) to generate the first and second filtered signals, the first diplexer (110) provides the first filtered signal to the second diplexer (104
