Abstract

A 1.9-dB NF K-band phased-array receiver (RX) is presented, which employs the hybrid packaged 65-nm CMOS beamformer and 0.1- $\mu \text{m}$ GaAs LNAs based on the fan-out wafer-level chip-scale packaging (WLCSP) technology. Power-efficient gain and phase tuning blocks are utilized to reduce power consumption. Temperature-healing design methodology is adopted to ensure nearly constant gain response versus temperature variations. The proposed phased-array RX only consumes 30.2-mW dc power per channel and achieves < 1.2-dB gain variation and < 0.9-dB NF variation from −40 °C to 85 °C. [ABSTRACT FROM AUTHOR]

Abstract

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. [ABSTRACT FROM AUTHOR]
