Patent ID: 11190146

Abstract:
Doherty power amplifier (PA) devices (e.g., packages and modules) including integrated output combining networks are disclosed. In embodiments, the Doherty PA device includes a first amplifier die having a first transistor with a first output terminal at which a first amplified signal is generated, a second amplifier die having a second transistor with a second output terminal at which a second amplified signal is generated, and an output combining network. The output combining network includes, in turn, a combining node integrally formed with the second amplifier die and electrically coupled to the second output terminal. At least one die-to-die bond wire electrically couples the first output terminal to the combining node. The at least one die-to-die bond wire has an electrical length, which is results in a 90 degree phase shift imparted to the first amplified signal between the first output terminal and the combining node.
