Installation for emission/reception of satellite signals

摘要

An emission/reception installation of satellite signals including a reflector to receive and emit radio signals, a unit integrating an LNB to transform radio signals into electrical signals in a first frequency band, to amplify the electrical signals in the first frequency band and to lower the first frequency band towards a first intermediate frequency band. The unit includes an emitter to amplify electrical signals in a second intermediate band having no common frequency with the first intermediate band, to raise the second intermediate band towards a second frequency band, to transform into radio signals the electrical signals in the second frequency band and to transmit these radio signals towards the reflector. The installation includes a box including a modulator to modulate electrical signals in the second intermediate band, an output to transmit electrical signals in the first intermediate band and a coaxial cable connecting the unit and the box.
