FIELD: communication.SUBSTANCE: invention relates to a system (SA) for amplification of signals generated by a unit (UGS) for generating satellite signals, comprising a first path (V1), having a first band-pass digital filter (F1) with finite impulse response and first digital-to-analogue converter (CNA1), means (MTF) for frequency transposition and an amplification device (DA). System further includes a second circuit (V2) having a second digital band-pass filter (F2) with finite impulse response, means (G) for amplification, located at output of said second digital filter (F2), driven generator (NCO) with numerical control with phase correction, a second digital-analogue converter (CNA2) and a device (S) for repeated combination for summation of signals of said first and second circuits (V1, V2).EFFECT: signal amplification.6 cl, 2 dwg |
