Abstract: An apparatus and a method include receiving, by a transmitter integrated circuit (IC) having a serial data communications interface, a digital transmit signal, and generating a first signal that is an analog radio frequency (RF) modulated signal based on the digital transmit signal and a second signal that is a phase-offset version of the first signal. An amplified signal is generated by amplifying the first signal and includes an amplified version of the first signal and an out-of-band distortion signal. A reduced-power signal is generated from the amplified signal. The reduced-power signal is subtracted from the second signal to output a distortion cancellation signal. An amplified distortion cancellation signal is generated by amplifying the distortion cancellation signal using an error amplifier. The amplified distortion cancellation signal and a delayed version of the amplified signal are combined to output an amplified version of the first signal with reduced distortion.

Abstract: An apparatus and method for uplink and/or downlink beamforming operation are disclosed. In one embodiment, each of a plurality of distributed secondary beamformer processors is associated with a respective region of an antenna array and associated with a respective beamforming submatrix. Each transmit or receive beamforming submatrix contains beamforming combining weights associated with antenna elements in the respective region of the antenna array. Further, each secondary beamformer processor uses the respective beamforming submatrix and a respective set of frequency-domain IQ data points (representing user data layers for transmission, or received FDIQ data from a corresponding set of transceiver ICs) to form a respective plurality of sets of beamformed frequency-domain IQ data points.

Abstract: Multi-level beamforming signal processing of frequency-domain inphase and quadrature data packets by a group of serially-connected transceivers. Packets intended for transmission during some frames are formatted according to subarray-level beamforming, while packets for transmission in other frames are formatted according to a full-dimensional level of beamforming.

Abstract: A method and apparatus for multi-tier beamforming are disclosed. The method includes receiving a first-tier beamformed frequency-domain IQ data packet and a plurality of second-tier beamformed frequency-domain IQ data packets at a transceiver integrated circuit (IC) subarray. Each transceiver IC of the transceiver IC subarray (i) forms a multi-tier beamformed frequency-domain IQ data set by combining beamformed frequency-domain IQ data from the first-tier beamformed frequency-domain IQ data packet with beamformed frequency-domain IQ data from selected ones of the second-tier beamformed frequency-domain IQ data packets, (ii) generates a discrete-time-domain signal from the multi-tier beamformed frequency-domain IQ data set, and (ii) generates a modulated radio frequency (RF) signal from the discrete-time-domain signal. The method further includes transmitting a multi-tier beamformed signal by transmitting respective modulated RF signals from the transceiver ICs of the transceiver IC subarray via a corresponding adjacent antenna element subarray.
