A full 4-channel 6.3Gb/s 60GHz direct-conversion transceiver with low-power analog and digital baseband circuitry

This paper presents a 60 GHz direct-conversion front-end and baseband transceiver, including analog and digital circuitry for the PHY functions. The 65 nm CMOS front-end consumes 319 mW and 223 mW in transmitting and receiving mode, respectively, and is capable of more than 7 Gb/s 16QAM wireless communication for every channel of the 60 GHz standards. The 40 nm CMOS baseband incorporating LDPC consumes 196 mW and 398 mW for 16QAM in transmitting and receiving mode, respectively. The entire system, using a 6dBi antenna built in an organic package, can transmit 3.1Gb/s over 1.8 m in QPSK and 6.3 Gb/s over 0.05 m in 16QAM.
