Abstract
Doherty power amplifiers with coupled line combiners are provided herein. In certain embodiments, a power amplifier system includes a carrier amplifier having a carrier output that provides a first radio frequency signal, a peaking amplifier having a peaking output that provides a second radio frequency signal, and a coupled line combiner that combines the first radio frequency signal and the second radio frequency signal to generate a radio frequency output signal at an output terminal. The coupled line combiner includes a first conductor line connected between the peaking output and a reference voltage, a second conductor line electromagnetically coupled to the first conductor line, a third conductor line connected between the carrier output and the reference voltage, and a fourth conductor line electromagnetically coupled to the third conductor line and connected between the output terminal and the second conductor line.
