Abstract:
1. A radio frequency integrated circuit (RFIC) comprises: baseband processing module configured to convert outbound data into an outbound baseband signal; an up-conversion module configured to convert the outbound baseband signal into an outbound RF signal; an adjust module configured to adjust coordinates of the outbound RF signal to produce a plurality of RF signal components, wherein the adjust module comprises, for each of the plurality of RF signal components: a plurality of power amplifiers configured to amplify the plurality of RF signal components output by the adjust module to produce a plurality of amplified RF signal components, wherein one or more of the plurality of power amplifiers have different gain settings based on the beamforming factor, and wherein the plurality of power amplifiers provide the plurality of amplified RF signal components to a plurality of antennas that transmit the plurality of amplified RF signal components to produce a beamformed RF signal having, in air, a desired coordinate.
