Lineär effektförstärkaranordning och ett förfarande
摘要
<p>An arrangement for linearizing an amplifier by a combination of two methods is described. In the first a predistorter 213 supplies harmonics to the main amplifier 214 in such a way as to counteract the distortion. In the second a feedforward arrangement subtracts in 219 a signal derived from the input of the main amplifier from a signal derived from the output to produce a distortion signal which is then subtracted from the main amplifier output to remove remaining distortion. The arrangement may be used in multi-carrier amplification.</p>
