Abstract
A communications apparatus which supports beamforming is described. The communications apparatus includes an array of N beam forming circuits, each of the N beamforming circuits including an RF signal input coupled to a phase shifter, an attenuator and a power amplifier. The communications apparatus further includes an array of antenna elements, each one of the N beamforming circuits including an output coupled to a different one of the antenna elements in the array of antenna elements; and a set of beam tables including control values used to selectively control elements of the beamforming circuits. The beam tables include sets of control values which are accessed and used to control components of the beamforming circuits depending on the beam angle to be used during a given time period. A feedback circuit generate EVM control information based on output signals from the beam forming circuits.
