Abstract
Asymmetric Doherty power amplifiers are disclosed. In certain embodiments, a Doherty power amplifier includes a carrier amplifier that generates a radio frequency carrier signal based on amplifying a radio frequency input signal, a peaking amplifier that generates a radio frequency peaking signal based on amplifying the radio frequency input signal, and a phase shifting and combining circuit configured to combine the radio frequency carrier signal and the radio frequency peaking signal to generate a radio frequency output signal. The carrier amplifier and the peaking amplifier have asymmetric amplifier sizes.
