An amplifier device has an input distributor block to which a radio-frequency input signal to be amplified can be fed via an input and that has a number of distributor elements connected in series. The input signal to be amplified is fed to the first distributor element as its input signal. Each distributor element splits the input signal supplied thereto into a divided signal and a remainder signal. With the exception of the first distributor element, each distributor element feeds its divided signal to a corresponding main amplifier of an amplifier block. With the exception of the last distributor element, each distributor element feeds its remainder signal to another distributor element as its input signal. Each main amplifier amplifies the divided signal fed to it into a corresponding amplified partial signal and feeds the amplified partial signal to a corresponding main combiner element of an output combiner block. Each main combiner element combines the amplified partial signal supplied to it with a further signal to form a sum signal. The main combiner elements are connected in series with one another so that, with the exception of the first main combiner element, the sum signal of another main combiner element is supplied to each main combiner element as a further signal. The sum signal emitted by the last main combiner element is supplied to an output. The distributor elements, the main amplifiers and the main combiner elements are designed such that the divided signals exhibit identical amplitudes among one another, the amplified partial signals exhibit identical amplitudes among one another and the delay from input to output is the same for all main amplifiers.
