This paper describes a 28GHz CMOS direct conversion transceiver with packaged 2×4 patch antenna arrays for 5G communication. Test results show good RF performances of Rx NF 6.7dB, Maximum Tx EIRP 31.5dBm (1PA Pout_sat =10.5dBm), LO integrated phase noise −37.8dBc (0.67°), Rx/Tx EVM around 2.2% (−33.1dB) at mid RF power, and well-fitted beam control capability.
