1. A system, comprising:
an amplifier having a first path and a second path; a power splitter coupled to the amplifier, the power splitter including:
a first adjustable attenuator connected to the first path,a second adjustable attenuator connected to the second path,a first adjustable phase shifter connected to the first path, anda second adjustable phase shifter connected to the second path; a controller coupled to the power splitter and including a serial peripheral interface, the controller being configured to receive instructions via the serial peripheral interface that, when executed by the controller, cause the controller to:
set an attenuation of the first path to a first attenuation value and an attenuation of the second path to the first attenuation value,determine a first phase shift of the first path and a second phase shift of the second path providing a maximum efficiency of the amplifier,set a phase shift of the first path to the first phase shift and a phase shift of the second path to the second phase shift, anddetermine a first attenuation of the first path and a second attenuation of the second path providing a maximum efficiency of the amplifier. |
