Abstract
A multi-carrier power amplifying arrangement has a number of amplifying devices, each of which includes a main amplifier and a linearizing device. Furthermore it includes a device signal for adding the adding output signals from the amplifying devices in phase, a device for detecting the average phase error of the amplified signals and for providing a compensating control signal. The compensating control signal is provided to each amplifying device at least to compensate for the average phase error.
