Abstract
An amplifier assembly includes a three or more way Doherty amplifier arrangement (DAA) having at least three amplifiers, including a main amplifier and at least two peak amplifiers. The DAA is within a dual-path package including a first-RF-input-lead and a second-RF-input-lead for receiving components of a split RF-input signal and providing the components to the DAA. A first-RF-output-lead and a second-RF-output-lead receive a split output signal from the DAA. The DAA includes a first-semiconductor-die and a second-semiconductor-die, each having thereon respective amplifier(s). The first-semiconductor-die includes a Doherty-splitter element splitting the RF-input signal from the first-RF-input-lead to provide an input to two amplifiers thereon and a Doherty-combiner element to combine an output from the two amplifiers. The Doherty-combiner element is connected to the first-RF-output-lead. The second-semiconductor-die amplifier(s) are connected to the second-RF-input-lead to provide an input to the amplifier(s) and to the second-RF-output-lead to receive an output from the amplifier(s).
