1. A system for delivering satellite signals to a receiver, 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 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 intermediate frequency band of signals and a third intermediate frequency band of signals;
a combiner for receiving the first intermediate frequency band of signals, the second intermediate frequency band of signals, and the third intermediate frequency band of signals, and combining the first intermediate frequency band of signals, the second intermediate frequency band of signals, and the third intermediate frequency band of signals into a delivery signal; and
a distribution unit, coupled to the combiner, for distributing the delivery signal to a plurality of outputs.

Abstract
A method, apparatus and system for combining signals in a satellite delivery system are disclosed. A first set of satellite signals are broadcast in a first frequency band, and downconverted to a first Intermediate Frequency (IF) band, and a second set of satellite signals are broadcast in a second frequency band and downconverted to a second IF band and a third IF band. A combiner receives the first, second, and third IF bands and combines the first, second, and third IF bands into a delivery signal. A distribution unit coupled to the combiner distributes the delivery signal to a plurality of outputs.
