Abstract
A high-frequency power amplifier for feeding an antenna of a nuclear magnetic resonance tomography apparatus has at least one amplifier stage that can emit a maximum output power within a first frequency band. Circuitry for frequency-dependently altering the maximum output power is connected to the amplifier stage, whereby the maximum output power within a second frequency band, that is higher than the first frequency band is higher than within the first frequency band.
