    Abstract: A multi-amplifier power management circuit and related apparatus are provided. The multi-amplifier power management circuit includes a transceiver circuit and an amplifier circuit, which are physically separated (e.g., in different integrated circuits). The amplifier circuit receives a radio frequency (RF) signal from the transceiver circuit and splits the RF signal into a number of RF transmit signals. The amplifier circuit includes a number of amplifiers configured to amplify the RF transmit signals. In examples discussed herein, the multi-amplifier power management circuit can be provided in an apparatus (e.g., a mobile communication device). The amplifier circuit may be collocated with a number of transmit antennas closer to an edge(s) of the apparatus. By collocating the amplifier circuit and the transmit antennas closer to the edge(s) of the apparatus, it may be possible to reduce RF signal radiation distance, thus helping to improve radiation efficiency and reduce heat dissipation in the apparatus.

    Abstract: In various implementations of a load modulated balanced amplifier (LMBA), a control signal is generated (e.g., automatically generated) based at least in part on an input signal. The LBMA generally comprises a balanced amplifier, an input splitter, and a control path. A common theme of the different variants described below is that we use a nonlinear characteristic to generate a power-dependent asymmetry in the relative output power levels of the balanced and control amplifiers. This power-depended asymmetry results in dynamic load modulation of the balanced amplifiers, which in turn provides improved efficiency. In one implementation, for example, an LMBA comprises a pair of primary amplifiers collectively providing a balanced amplifier and a control amplifier coupled to the balanced amplifier and adapted to provide a control signal to the balanced amplifier.

  • Patent number: 10296602
    Abstract: Methods, apparatus, systems, and computer-readable media for assigning a real-time clock domain timestamp to sensor frames from a sensor component that operates in a non-real-time time-domain. In some implementations, a real-time component receives capture instances that each indicate capturing of a corresponding sensor data frame by the sensor component. In response to a capture output instance, the real-time component or an additional real-time component assigns a real-time timestamp to the capture output instance, where the real-time timestamp is based on the real-time clock domain. Separately, a non-real-time component receives the corresponding sensor data frames captured by the sensor component, along with corresponding metadata. For each sensor data frame, it is determined whether there is a real-time timestamp that corresponds to the data frame and, if so, the real-time timestamp is assigned to the sensor data frame.

  • Patent number: 10187130
    Abstract: Using High-beam and low-beam transmission signals that have different antenna tilts, different beam-widths, and different polarizations than one another may provide performance advantages in wireless networks. The high-beam transmission signal and the low-beam transmission signal may have orthogonal polarizations. For example, the high-beam transmission signal and the low-beam transmission signal may be linearly polarized signals having different electromagnetic field (E-field) polarization angles with respect to the y-axis, e.g., +/? forty-five degrees with respect to a vertically polarized wave. As another example, the high-beam transmission signal may be a vertically polarized signal, and the low-beam transmission signal may be a horizontally polarized signal, or vice-versa. In addition to having orthogonal polarizations, the low-beam transmission signal may have a greater antenna beam down-tilt angle, and a wider beam-width than the high-beam transmission signal.
