Abstract:
1. A device for receiving signals from a transmission system, said system including a broadcast transmitter and a gapfiller transmitter, said device comprising: a first feed receiving a first signal in a first frequency band from a broadcast transmitter; a second feed receiving a second signal in a second frequency band from a gapfiller transmitter; a local oscillator producing a local oscillator signal; a first multiplier coupled to the local oscillator for multiplying the local oscillator signal by a first factor producing a first multiplied signal; a second multiplier coupled to the local oscillator for multiplying the local oscillator signal by a second factor producing a second multiplied signal; a first mixer for mixing the first multiplied signal with the first signal producing a first intermediate frequency (IF) signal; a second mixer for mixing the second multiplied signal with the second signal producing a second IF signal wherein the first IF signal and the second IF signal each include at least one channel having a common IF center frequency; a filter for filtering the second IF signal producing a filtered second IF signal; and a combiner for combining the filtered second IF signal and the first IF signal.
