Patent ID: 7570117

Claim:
An amplifier device comprising: an input distributor comprising a plurality of distributor elements connected in series, including a first distributor element in the series connection and a last distributor element in the series connection, said first distributor element having an input supplied with a radio-frequency input signal and each successive distributor element having an input signal that is an output signal of an immediately preceding one of said distributor elements in the series connection; each of said distributor elements splitting the input signal thereto into a divided signal and a remainder signal, and for each of said distributor element except said last distributor element, the remainder signal thereof forming the output signal that is supplied as an input signal to a next distributor element in the series connection; a plurality of amplifiers; except for said first distributor element, each of said distributor elements respectively supplying the divided signal thereof to one amplifier in said plurality of amplifiers, wherein the divided signal is amplified to form an amplified partial signal; a plurality of combiner elements connected in series, including a first combiner element in the series connection of combiner elements and a last combiner element in the series connection of combiner elements; each of said combiner elements being supplied with a further signal as an input thereto and forming a sum signal from said further signal and the amplified partial signal supplied thereto and, except for said first combiner element, each of said combiner elements supplying said sum signal as the further input signal to a next combiner element in the series connection, said first combiner element being supplied with a separate further signal; a device input connected to the input of said first distributor element, and a device output connected at least indirectly to the output of said last combiner element; and said distributor elements being configured to emit the divided signals with identical amplitudes, said amplifiers being configured to emit the amplified partial signals with identical amplitudes, and said plurality of distributor elements, said plurality of amplifiers, and said plurality of combiner elements being configured to make a delay from the device input to the device output identical for each amplifier in said plurality of amplifiers.
