Abstract:
Systems and methods related to linear load modulated power amplifiers. A power amplifier (PA) system can include a divider that splits a signal into two portions, a first portion directed to an attenuator that attenuates the first portion so that the first portion and the second portion have different powers and a second portion directed to a phase shift component that shifts a phase of the second portion so that the first portion and the second portion have different phases. The PA system can also include a Doherty amplifier circuit where a carrier amplifier amplifies the attenuated first portion and a peaking amplifier amplifies the phase-shifted second portion. The carrier amplifier includes a Class AB driver stage and a Class B output. The peaking amplifier includes a Class B driver stage a Class B output stage.

Claim (Index 12):
A power amplifier (PA) module comprising:\n a packaging substrate configured to receive a plurality of components; and a PA system implemented on the packaging substrate, the PA system including a divider configured to receive an input signal and to split the input signal into a first portion and a second portion, the PA system also including an attenuator configured to receive the first portion and to attenuate the first portion so that the first portion and the second portion have different powers, the PA system also including a phase shift component configured to shift a phase of the second portion so that the first portion and the second portion have different phases, the PA system also including a Doherty amplifier circuit including a carrier amplifier configured to amplify the attenuated first portion to yield an amplified first portion and a peaking amplifier configured to amplify the phase-shifted second portion to yield an amplified second portion, the carrier amplifier having a driver stage configured to operate in a Class AB biasing mode and an output stage configured to operate in a Class B biasing mode, the peaking amplifier having a driver stage configured to operate in a Class B biasing mode and an output stage configured to operate in a Class B biasing mode.
