| 摘要 |
The invention relates to a device (3) for the amplification of a signal (S1) from an antenna (2) for receiving waves in a first frequency band, particularly of the radio frequency type. The inventive device comprises signal amplification means (6, 8) and means (7) for converting the signal from a first frequency band to a second lower frequency band. The device also comprises means (10) for controlling the amplification means, taking a signal derived from the output signal (S2) of the amplification device (3) as an input signal (S4). |
