Satoshi Kondo, Tomohiro Ueno, Yasuaki Takeuchi, Tatsuya Yamaguchi, Ahmed Musa, Rui Wu, Masaya Miyahara, Akira Matsuzawa The RX conversion gain is more than 20dB, excluding the PCB loss. SNDR at the center frequency of 61.56GHz is estimated from the measured IM3 of the RX PCB, and the measured noise figure of the stand-alone LNA. A peak SNDR is 35dB excluding the PCB loss. The power consumptions of LNA, two differential amplifiers, two mixers, and two BB amplifiers are 41mW, 19mW, 23mW, and 30mW, respectively. Tokyo Institute of Technology, Tokyo, Japan This paper presents a 64-QAM 60GHz CMOS transceiver, which achieves a TX-to-RX EVM of -26.3dB and can transmit 10.56Gb/s in all four channels defined in IEEE802.11ad/WiGig. By using a 4-bonded channel, 28.16Gb/s can be transmitted in 16QAM. The front-end consumes 251mW and 220mW from a 1.2-V supply in transmitting and receiving mode, respectively.
