1. A high-frequency power amplifier for feeding an antenna of a nuclear magnetic resonance tomography apparatus, comprising:
- an amplifier stage which has a maximum power output within a first frequency band; and
circuitry means connected to said amplifier stage for altering said maximum output power for producing a maximum output power in a second frequency band, said second frequency band being higher than said first frequency band and said maximum output power in said second frequency band being higher than said maximum output power in said first frequency band.

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.
