概要 | This paper presents a 60-GHz CMOS transceiver targeting the IEEE 802.11ay standard. A calibration block for local oscillator feedthrough (LOFT) and I/Q imbalance featuring high accuracy and low power consumption is integrated with the transceiver. With the help of the proposed calibration, this paper is capable of boosting the data rate with higher order modulation scheme and wider channel-bonding bandwidth, which are demanded by IEEE 802.11ay. At the same time, it maintains the compatibility with the existing IEEE 802.11ad standard. This paper reports a two-channel-bonding data rate of 24.64 Gb/s in 128 quadrature amplitude modulation (QAM). The corresponding TX-to-RX error vector magnitude (EVM) is −26.1 dB.
Furthermore, a four-channel-bonding data rate of 42.24 Gb/s in 64 QAM is realized with a single-element transceiver. The measured maximum data rate is 50.1 Gb/s in 64 QAM, which is the highest data rate achieved in the 60-GHz and. The power consumption is only 169 mW in the transmitting mode and 139 mW in the receiving mode. 副筆 |
