| 摘要 |
The invention relates to a Doherty amplifier (100) comprising a primary amplification path (110) for amplifying an input signal (in), a plurality of secondary amplification paths (120a, 120b) for amplifying specific frequency sub-ranges of said input signal (in), and signal processing means (130) which comprise at least two preprocessing branches (132, 134, 136), wherein a first preprocessing branch (132) is configured to supply said primary amplification path (110) with a primary input signal (in1) derived from said input signal (in), and wherein at least one further preprocessing branch (134, 136) is configured to supply at least one of said secondary amplification paths (120a, 120b) with a secondary input signal (in2, in3) derived from said input signal (in).
