Abstract:
An apparatus is disclosed for flexible beamforming using frequency-division multiplexing. In an example aspect, an apparatus includes an antenna array and a wireless transceiver with two or more dedicated receive paths respectively coupled to two or more antenna elements of the antenna array, two or more mixers, a first combiner, a second combiner, and a switching circuit. The first combiner has a first input coupled to a first dedicated receive path and an output coupled to an input of a first mixer. The second combiner has a first input coupled to an output of the first mixer and a second input coupled to an output of a second mixer. The switching circuit is configured to selectively connect a second dedicated receive path to a second input of the first combiner or connect the second dedicated receive path to an input of the second mixer.
