Abstract:
1. An adjustable radio frequency power splitter comprising: a power splitter input; a first power splitter output coupled to a first amplifier; a second power splitter output coupled to a second amplifier; a power divider with a power divider input coupled to the power splitter input, a first divider output, and a second divider output; a first adjustable phase shifter coupled to the first divider output; a first adjustable attenuator coupled to the first divider output and series coupled with the first adjustable phase shifter, wherein the first adjustable phase shifter and the first adjustable attenuator are configured to provide a first output signal at the first power splitter output; a second adjustable phase shifter coupled to the second divider output; a second adjustable attenuator coupled to the second divider output and series coupled with the second adjustable phase shifter, wherein the second adjustable phase shifter and the second adjustable attenuator are configured to provide a second output signal at the second power splitter output; an interface; and a controller configured to receive, via the interface, data indicating phase shifts to be applied by the first and second adjustable phase shifters and attenuation levels to be applied by the first and second adjustable attenuators, and to control, based on the data, the phase shifts and attenuation levels applied by the first and second adjustable phase shifters and the first and second adjustable attenuators.
