Abstract
Systems and methods related to linear load modulated power amplifiers. A power amplifier (PA) system can include an input circuit configured to receive a radio-frequency (RF) signal and split the RF signal into a first portion and a second portion. The PA system can further include a Doherty amplifier circuit including a carrier amplifier coupled to the input circuit to receive the first portion and a peaking amplifier coupled to the input circuit to receive the second portion. The first portion and the second portion can have different phases and/or different powers. The PA system can further include an output circuit coupled to the Doherty amplifier circuit. The output circuit can be configured to combine outputs of the carrier amplifier and the peaking amplifier to yield an amplified RF signal.
