Patent abstract
A controller for an RF amplifier, in particular for an RF amplifier of an MR tomograph, contains an RF control element that finely adjusts an RF signal requiring to be fed to the RF amplifier in magnitude and phase using LF control parameters of a control element regulator, a power meter that measures the input power of the RF signal fed to the RF amplifier and a pre-emphasizer that applies correction values dependent on the input power to the LF control parameters to compensate a power-dependent characteristic curve of the RF amplifier.
