Abstract: The present disclosure is directed to an apparatus (300) and method (400, 600) for controlling a filter circuit (500) in a signal communication device (300). The apparatus (300) and method (400, 600) of the present disclosure receives (410) an indication of a plurality of channels used to transmit upstream communication signals in an upstream communication portion of a frequency range. Furthermore, the apparatus (300) and method (400, 600) of the present disclosure determines (420) a maximum frequency value among all frequencies used by the plurality of channels based on the indication and adjusts (430) a filter response in a filter circuit (500) used to separate the upstream communication signals from the downstream communication signals in a communication device (300) based on the determined uppermost frequency value.

Abstract: There is provided a communication circuit (200). In an exemplary embodiment, the communication circuit (200) comprises a circuit (220) that is adapted to receive a terrestrial signal corresponding to a terrestrial frequency spectrum (504) and a satellite signal corresponding to at least one user band (506a, 506b, 506c) and to create an output signal that combines the terrestrial frequency spectrum (504) and the at least one user band (506a, 506b, 506c). An exemplary communication circuit (200) additionally comprises a circuit (300) that is adapted to reposition a satellite frequency spectrum (402, 406, 410, 414) in an unused frequency band of the output signal.
