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.
