Abstract
A Doherty power amplifier is provided that includes a main amplifier device and an auxiliary amplifier device. The Doherty power amplifier further includes a phase compensation network. The phase compensation network is configured to maintain a substantially constant phase of one of an output signal from the main amplifier device or an output signal from the auxiliary amplifier device across a range of input powers. The Doherty power amplifier further includes an impedance inverter for power combining an output signal of the main amplifier device with an output signal of the auxiliary amplifier device.
