Patent number: 10038407Abstract: A die is described comprising at least one 3-way Doherty amplifier comprising a main stage, a first peak stage and a second peak stage. An input is connected to an input network which is connected to the main stage, first peak stage and second peak stage. The input network includes a first impedance connected to an input of the first peak stage and providing a ?90° phase shift and a second impedance connected to an input of the second peak stage and providing a 90° phase shift. An output is connected to an output network which is connected to the main stage, first peak stage and second peak stage. The output network includes a third impedance connected to the output of the first peak stage and providing a 180° phase shift and a fourth impedance connected to the output of the main stage and providing a 90° phase shift.Type: GrantFiled: August 7, 2015Date of Patent: July 31, 2018Assignee: Ampleon Netherlands B.V.Inventors: Xavier Moronval, Jean-Jacques Bouny, Gerard Bouisse
