| Abstract(in English) | This work demonstrates a 39-GHz CMOS phased-array beamformer with the bi-directional Doherty PA-LNA. An inter-element mismatch compensation technique is introduced for improving the shared-LUT DPD performance over the PVT variations. By utilizing the proposed mismatch compensation, the measured 64-QAM OFDMA-mode EVM and ACLR with the shared-LUT DPD are improved from −22.4dB to −25.0dB and from −28.7dBc to −32.1dBc, respectively. |
