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.
