| 摘要 |
<p>The invention relates to an amplifier (1) for amplification of an RF input signal (RF in), comprising: an output stage (2), a modulator (3) for providing a signal-specific supply voltage (V) to the output stage (2) based on an envelope (4) of the RF input signal (RF in), and at least one adaptive output impedance matching unit (9a to 9c) for adapting an output impedance of the output stage (2), wherein the amplifier (1) is designed to adapt the at least one adaptive output matching unit (9a to 9c) based on the signal-specific supply voltage (V) that is provided to the output stage (2) and preferably also on a specific load condition. The invention also relates to a base station and to a communication network comprising such an amplifier (1), as well as to a method for power amplification using such an amplifier (1).</p> |
