Abstract
Official abstract text for this publication.
Exemplary embodiments are directed to beamforming. A device may include a plurality of mixers, wherein each mixer is configured to receive at least one of a quadrature signal and an in-phase signal. The device may further include at least one RF phase rotator coupled to an output of each of the plurality of mixers and configured for rotating an envelope of the at least one of the quadrature signal and the in-phase signal to generate at least one of a rotated in-phase signal and a rotated quadrature signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A device, comprising: a plurality of mixers, each mixer configured to convey at least one of a quadrature signal and an in-phase signal; and at least one RF phase rotator coupled to an output of each of the plurality of mixers and configured for rotating independent of a carrier signal an envelope of the at least one of the quadrature signal and the in-phase signal to generate at least one of a rotated in-phase signal and a rotated quadrature signal.…
