| 摘要 |
The present invention concerns an emission/reception installation (1) of satellite signals comprising a reflector (3) suited to receive and emit radio signals, a unit (2) integrating an LNB (4) suited to transform radio signals into electrical signals in a first frequency band concentrated by the reflector (3), 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 (2) further comprises an emitter (TX) suited 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 (S), to transform into radio signals the electrical signals in the second frequency band and to transmit these radio signals towards the reflector (3). The installation (1) further comprises a box (21) including a modulator (25) suited to modulate electrical signals in the second intermediate band, an output (32) suited to transmit electrical signals in the first intermediate band and a coaxial cable (20) connecting the unit (2) and the box (21). |
