The paper provides a detailed overview of large-scale mm-Wave integrated phased array technology, discussing design considerations, challenges, and trade-offs, as well as the high yield and low-cost production capabilities of both CMOS and hybrid PCB technologies. Demonstrators of integrated phased arrays at different scales are presented, achieving impressive EIRP values. Relevant phased-array transceivers and antennas from recent literature are also discussed.
Large-scale millimeter-wave (mm-Wave) integrated phased array is the key technology to enable broadband 5G and satellite communications. This paper details the design considerations, challenges and trade-offs of mm-Wave integrated phased arrays based on bulk CMOS and multi-layer hybrid PCB technologies. Both technologies attain high yield and low cost for mass production. Important beamforming building blocks are addressed and compared in detail. Demonstrators of integrated phased arrays are presented from circuit to board levels. The 1024- and 4096-element integrated phased arrays achieve the EIRP of 72.5 and 84.0 dBm respectively. Finally, relevant phased-array transceivers and antennas from the recent literature are discussed.
