    Abstract: Systems, methods, and computer-readable media are provided for hybrid beamforming. An example method can include determining 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; determining analog beamforming weights associated with the groups of analog beamforming circuits, the analog beamforming weights comprising inverses of the digital beamforming weights; determining calibration offsets estimated to put analog beamforming paths associated with the groups of analog beamforming circuits in a desired phase and gain relationship to each other; and varying, based at least partly on the calibration offsets, a signal phase shift across the analog beamforming paths associated with the groups of analog beamforming circuits.

    Abstract: In one example, a system for use with an antenna assembly is described. The system may include a mast having a first end configured to be coupled to a mount and a second end configured to be coupled to the antenna assembly. A bulkhead connector may be disposed within an inner bore of the mast, wherein the bulkhead connector includes a biasing member moveable between a first position and a second position, wherein the biasing member is biased to the first position and moveable to the second position when urged by a force. The system may further include a mount including a mount connector configured to mate with the bulkhead connector, wherein the bulkhead connector is in the first position when mated or unmated with the mount connector, and wherein the bulkhead connector is in the second position when being partially mated or being partially unmated from the mount connector.

    Abstract: In an embodiment, an apparatus includes a source device including a first current limiter and a second current limiter in parallel with each other and a first transformer and a second transformer; a load device includes a third transformer and a fourth transformer in parallel with each other; and an Ethernet cable is electrically coupled between the source device and the load device, the Ethernet cable including first twisted pair lines and second twisted pair lines. A direct current (DC) voltage is provided to the first current limiter and the second current limiter, the first transformer is electrically coupled to an output of the first current limiter, and the second transformer is electrically coupled to an output of the second current limiter. The DC voltage is transmitted to the third transformer and the fourth transformer in parallel with each other via the first twisted pair lines and the second twisted pair lines. The first twisted pair lines and second twisted pair lines are included in an Ethernet cable electrically coupled between the source device and the load device.
