Abstract: Described herein are systems with switchable circuitry configured to selectively couple transmitter outputs to processing hardware, which may selectively route subsets of distortion measurements from transmitters for DPD processing that compensates for the measured distortion. The switchable nature of the distortion measurement propagation paths permits the paths to be made substantially shorter than static paths, resulting in improved (e.g., reduced and/or more uniform) attenuation and/or phase change across a transceiver array. In one example, measurement propagation paths may be no longer than a row or column of the array. In some embodiments, systems described herein may be suitable for implementation at mmW transmit and/or receive frequencies, where the length of measurement paths may have a significant impact on attenuation and phase changes.

Abstract: Described herein are phased array and transceiver systems with distortion measurement circuitry configured to obtain distortion measurements of system transmitters and provide the distortion measurements to receive beamforming components of the system. Such systems advantageously make use of existing beamforming components of the system to additionally route distortion measurements for baseband DPD processing. Such systems may not need external components to measure signals radiated by antennas of the system or dedicated paths linking system transmitters directly to a baseband processor. In some embodiments, receive beamforming components may be configured to sum distortion measurements from each transmitter to create an aggregate distortion measurement usable as representative of the average transmitter for DPD processing.
