An amplifier device for a mode antenna has a number of amplifiers and a number of outputs. An input signal is fed to each amplifier, which is amplified by the respective amplifier into an amplified input signal. The amplified input signals are fed to an output matrix arranged after the amplifiers. Respective output signals are emitted by the output matrix at the outputs. The output matrix causes each amplified input signal to supply an output signal contribution for each output signal. Each output signal contribution of each output signal has an output-side contribution offset in relation to the corresponding amplified input signal, which depends on the amplified input signal that supplied the output signal contribution, and the output signal to which the output signal contribution contributes. The amplifier device is especially able to be used in a transmit arrangement for radio-frequency signals.
