Abstract

A radio-frequency acquisition device for a magnetic resonance tomography apparatus has at least one reception antenna for acquisition of magnetic resonance signals and with an amplifier device to amplify acquired magnetic resonance signals. The amplifier device has an input transistor and a transformation device to transform the source impedance of the acquisition antenna into a source impedance adapted to the input transistor, and wherein the transformation device can be switched between at least two transformation ratios.
