This work presents the world’s first D-band dual-polarized (DP) multi-input and multi-output (MIMO) phased-array transceiver targeting 6G user equipment (UE), fabricated in a 65nm CMOS process. The proposed transceiver achieves a maximum data rate of 144 Gbps. Each IC integrates 4 vertical (V) and 4 horizontal (H) polarized TRX elements in a compact layout, resulting in power consumption per element of 124 mW in TX and 90 mW in RX. Furthermore, the transceiver is embedded within a high-power-density antenna-in-package (AiP) module, enabling long-distance single-stream communication up to 50 meters.
