Abstract: Systems, methods, and computer-readable media are provided for hybrid beamforming. An example method can include determining a plurality of digital beamforming weights associated with a plurality of digital beamforming paths between digital beamformers and groups of analog beamforming circuits in a phased array antenna, each digital beamforming path being coupled to a group of analog beamforming circuits and each analog beamforming circuit being coupled to a respective set of antenna elements of the phased array antenna, and determining analog beamforming weights associated with the groups of analog beamforming circuits. The analog beamforming weights are estimated to put analog beamforming paths associated with the groups of analog beamforming circuits in a desired phase and gain relationship with each other. The method can include varying, based at least partly on the analog beamforming weights, a signal phase shift across the analog beamforming paths associated with the groups of analog beamforming circuits.

Abstract: Systems, methods, and non-transitory media are provided for cross-coupling modeling and compensation. An example method can include determining one or more cross-coupling coefficients representing electrical cross-coupling between a first signal path through a component and a second signal path through the component; based on the one or more cross-coupling coefficients, determining a first modified beamforming weight for a first signal associated with the first signal path through the component and a second modified beamforming weight for a second signal associated with the second signal path through the component, wherein the first and second modified beamforming weights compensate for the electrical cross-coupling between the first signal path through the component and the second signal path through the component; applying the first modified beamforming weight to the first signal associated with the first signal path; and applying the second modified beamforming weight to the second signal associated with the second signal path.

Abstract: Systems and techniques for distributing reference signals are disclosed. For example, a method includes generating, by a first phase-locked loop (PLL) included in a first beamformer (BF) chip, a first local oscillator (LO) signal; generating, by a second PLL included in a second BF chip, a second LO signal; and in a first BF configuration, transmitting radio frequency (RF) signals by a plurality of antenna elements based on the first LO signal. A first subset of the plurality of the antenna elements is associated with the first BF chip and a second subset of the plurality of antenna elements is associated with the second BF chip. The method includes, in a second BF configuration, receiving RF signals by the first subset of the plurality of antenna elements and the second subset of the plurality of antenna elements based on the second LO signal.
