A 250-mW 60-GHz CMOS Transceiver SoC Integrated With a Four-Element AiP Providing Broad Angular Link Coverage

In this article, we present a low-power, small formfactor, 60-GHz packaged radio featuring broad beam coverage. We increase angular coverage by beam switching between two orthogonally pointed low directivity beams that are created using two different antennas integrated in package. The resulting wide angular coverage of the radio makes radio links robust to movement and rotation; this improvement ...
