  • Publication number: 20200379493
    Abstract: Methods of powering a radio that is mounted on a tower of a cellular base station are provided in which a direct current (“DC”) power signal is provided to the radio over a power cable and a voltage level of the output of the power supply is adjusted so as to provide a substantially constant voltage at a first end of the power cable that is remote from the power supply. Related cellular base stations and programmable power supplies are also provided.

  • Publication number: 20200358476
    Abstract: A small cell base station antenna includes a first backplane, a first linear array of radiating elements extending forwardly from the first backplane, a second backplane that is opposite the first backplane and a second linear array of radiating elements extending forwardly from the second backplane. The first backplane is inclined at a first oblique angle with respect to a vertical axis and the second backplane is inclined at a second oblique angle with respect to the vertical axis.

  • Patent number: 10833529
    Abstract: Systems and methods for high efficiency power conversion are provided. In one embodiment, a high efficiency electric power converter circuit comprises: an electric power converter that provides a first electric power output; a storage device that provides a second electric power output; and a power arbitrating switch that receives the first and second electric power outputs and selectively supplies a third electric power output using at least one of the first electric power output and the second electric power output. The switch is configured with a first sensor to measure a charge level of the device and with a second sensor to measure a power demand drawn from the third electric power output. The power arbitrating switch switches the third electric power output between being supplied from the first electric power output and being supplied from the second electric power output based on the power demand and the charge level.

  • Patent number: 10727893
    Abstract: Reconfigurable front-end module for carrier aggregation. In some embodiments, a front-end module can include a plurality of signal ports and a plurality of antenna ports. The front-end module can further include a switch assembly configured to route signals along one or more of a plurality of filtering paths between the signal ports and the antenna ports. Each of the filtering paths can include a filter, and the filtering paths can be configured to allow the antenna ports to be combined outside of the front-end module to accommodate a corresponding antenna configuration. The filtering paths can be further configured to maintain desirable filtering performance levels for different combinations of the antenna ports outside of the front-end module corresponding to the different antenna configurations.

  • Publication number: 20190187192
    Abstract: A power metering device includes a tap unit including a clamp for engaging a coaxial cable and a probe for electrically coupling to a center conductor of the coaxial cable without damaging the center conductor. A power consumption meter and a power port are electrically connected to the probe. A power transformer is optionally connected between the probe and the power port. A housing surrounds the meter and transformer. The power port supplies power to a customer device, and the meter measures an amount of power passing through the power port. The power consumed by the customer device is reported by the meter to a modem within the housing. The modem may utilize the probe and the center conductor of the coaxial cable to send power consumption data to a service provider, so that an operator of the customer device may be billed and/or the customer device may be controlled to limit its power consumption. Further, the modem may transfer data between the customer device and the service provider.
