摘要： A system and method of calibrating an amplifier are presented. The amplifier has a first amplification path and a second amplification path. A first state of the amplifier is identified defining a first phase shift of the first path and a second phase shift of the second path resulting in a maximum efficiency of the amplifier when an attenuation of the first path and an attenuation of the second path are set to first attenuation values. The attenuation of the first path and the attenuation of the second path is set to achieve a maximum efficiency of the amplifier when the phase shift of the first path and the phase shift of the second path are set according to the first state.

摘要： A device includes a power splitter configured to couple to an amplifier having a first path and a second path. The device includes a controller coupled to first and second variable attenuators and first and second adjustable phase shifters. The controller is configured to monitor a phase shift and an output power of each of the first path and second path of the amplifier, and adjust at least one of the first and second variable attenuators and the first and second adjustable phase shifters based upon the phase shift and the output power of each of the first path and second path of the amplifier to modify an input signal to the first path or the second path of the amplifier.
