Example systems and methods described herein relate to radio communication architectures and techniques for beamforming and down-conversion without a priori knowledge of the source location or frequency. An example radio receiver includes a plurality of antenna elements that include a first element, a second element, and a third element. The radio receiver also includes a plurality of mixers coupled to the plurality of antenna elements and a combiner coupled to the plurality of antenna elements. A signal incident on the first element is mixed with itself via a first mixer of the plurality of mixers. An output of the first mixer is mixed with a signal incident on the second element via a second mixer of the plurality of mixers, and an output of the second mixer is combined via the combiner with a signal incident on the third element.
