Abstract: An adjustable power splitter includes: a power divider with an input and a first and second divider output; a first adjustable phase shifter and first adjustable attenuator series coupled to the first divider output and providing a first power output; a second adjustable phase shifter and second adjustable attenuator series coupled to the second divider output and providing a second power output; an interface; and a controller. The controller is 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.
