Abstract
Doherty power amplifiers (DPAs), and related circuits, devices, systems and methods of operation, are disclosed herein. In an example embodiment, a system includes a first transistor device operable as a carrier amplifier, a second transistor device operable as a peaking amplifier, and at least one first integrated passive device (IPD) coupled between a combining node and each of carrier and peaking amplifier output ports. The system includes a first frequency-corrective network coupling the carrier amplifier output port with the node, where the network is formed at least in part by the at least one first IPD and is configured to operate as a first quasi-inverter network that includes a low-pass network. Additionally, the system includes a second frequency-corrective network coupling the peaking amplifier output port with the node, where the network is formed at least in part by the at least one first IPD and includes a bandpass network.
