Abstract: The power combiner circuit includes a transformer having a first primary coil coupled to a first power amplifier (PA), a second primary coil coupled to a second PA, and a secondary coil. The secondary coil supplies a current to an antenna based on a first direction of a first phase of a first amplified constant-envelope signal in the first primary coil with respect to a second phase of a second amplified constant-envelope signal in the second primary coil. A first load impedance is associated with the first PA and a second load impedance is associated with the second PA. The first load impedance and the second load impedance receive currents from the first PA and second PA, respectively, based on a second direction of the first phase of the first amplified constant-envelope signal with respect to the second phase of the second amplified constant-envelope signal.

Abstract: A system, in a programmable active reflector (AR) device associated with a first radio frequency (RF) device and a second RF device, receives a request and associated metadata from the second RF device via a first antenna array. Based on the received request and associated metadata, one or more antenna control signals are received from the first RF device. The programmable AR device is dynamically selected and controlled by the first RF device based on a set of criteria. A controlled plurality of RF signals is transmitted, via a second antenna array, to the second RF device within a transmission range of the programmable AR device based on the associated metadata. The controlled plurality of RF signals are cancelled at the second RF device based on the associated metadata.
