1. A system for delivering satellite signals, comprising:
- a first set of satellite signals broadcast in a first frequency band, wherein the first set of satellite signals is downconverted to a first intermediate frequency (IF) band of signals;
a second set of satellite signals broadcast in a second frequency band, wherein the second set of satellite signals is downconverted to a second IF band of signals and a third IF band of signals, wherein the first IF band of signals, the second IF band of signals, and the third IF band of signals are present in a combined IF signal on a cable; and
an upconverter, comprising;
a splitter, coupled to the cable, for dividing the combined IF signal;
a first path, coupled to a first output of the splitter, for selectively passing the combined IF signal to an output of the upconverter;
a second path, coupled to a second output of the splitter, for removing the first IF band of signals from the combined IF signal and for upconverting the first IF band of signals to the third IF band of signals; and
a third path, coupled to the first output of the splitter, for selectively removing the third IF band of signals from the combined IF signal and subsequently diplexing the upconverted first IF band of signals with a remainder of the combined IF signal into a diplexed signal, the diplexed signal selectively delivered to the output of the upconverter.
