Ultra-high-data-rate 60-GHz CMOS transceiver for future radio access network

This paper presents 60-GHz CMOS transceivers aiming for the IEEE802.11ay standard, which are integrated with 4-channel bonding techniques. The transceivers can be classified into two categories: a 1-stream transceiver and a 2-stream frequency-interleaved (FI) transceiver. The transceivers are both fabricated in a standard 65-nm CMOS technology. The 1-stream transceiver achieves a TX-to-RX EVM of -17dB and can transmit 28.16Gb/s in 16QAM by using a 4-bonded channel. The front-end consumes 251mW and 220mW from a 1.2-V supply in transmitting and receiving mode, respectively. The 2-stream FI transceiver achieves 42.24Gb/s data-rate in 64QAM by operating two FI transceivers at the same time. Each FI transceiver uses 2-channel-bonded spectrum with different carrier frequencies, which realizes the TX-to-RX EVM of -24.1dB and -23.0dB, respectively. The whole transceiver consumes 544mW and 432mW from a 1.2V supply in transmitting and receiving mode, respectively.
