Abstract: Aspects of the disclosure relate to devices, wireless communication apparatuses, methods, and other aspects of spur suppression in millimeter wave receivers. In one aspect a local oscillator (LO) source is coupled to a quadrature generation circuit having a first output for a first LO signal, and a second output for a second LO signal 90 degrees out of phase with the first LO signal. Each output is coupled to an LO driver, and outputs of the LO drivers a coupled at a first power connection to provide spur suppression associated with a phase difference between the first LO signal and the second LO signal. Similar connections are provided at outputs of first and second mixers for spur suppression.

Abstract: Aspects described herein include devices and methods for an envelope tracking power supply. In some aspects, the envelope tracking power supply includes an envelope signal input port, an output power port, an input interface circuit coupled to the envelope signal input port, sensing and conditioning circuitry, and amplifier circuitry coupled between the input interface circuit and the sensing and conditioning circuitry, the amplifier circuitry having one or more control inputs. The envelope tracking power supply additionally includes switcher circuitry coupled to the output of the sensing and conditioning circuitry, and the output power port, and the supply further includes output filter circuitry coupled to the output power port and machine learning circuitry configured to receive state tracking data for performance of a transmit power amplifier (PA) that receives power via the output power port.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus detects a level of power received from each of a plurality of sources. The apparatus directs the power received from a first source to a charging circuit and directs the power received from at least a second source to the charging circuit. The apparatus directs the power received from the first source to the charging circuit by comparing the detected level of the power with a threshold and directing the power to the charging circuit based on a result of the comparison. The apparatus directs the power received from the at least a second source to the charging circuit by comparing the detected level of the power with the threshold and directing the power to the charging circuit based on a result of the comparison.
