The approval of IEEE 802.11aj in 2018 enabling the indoor short range application of 45 GHz millimeter-wave (mm-wave) frequency band in China. This paper presents an IEEE 802.11aj mm-wave transceiver with printed on-board antenna, operating from 42.3 to 48.4 GHz, in a 0.13 μm SiGe:C BiCMOS technology. The transmitter chip achieves a maximum output power of 18.7 dBm at 44 GHz and delivers an OP1dB of 14.6 to 16.4 dBm at the IEEE 802.11aj frequency band. The receiver chip achieves 3.8 to 4.1 dB noise figure (NF),-18.7 to-22 dBm input 1 dB compression point and a conversion gain better than 43.8 dB in the IEEE 802.11aj frequency band. The measured printed on-board Yagi-Uda antenna achieves 9 dBi gain. The power consumption is 478 mW and 186 mW in the transmitter and the receiver modes respectively. In the system wireless data transmission measurement, the measured TX-to-RX EVM in 64-QAM is-29 dB (3.55 %) at a 1 meter distance. Compared to other state-of-arts, the transmitter's output power is the highest, and the demonstrated transceiver achieves the highest performance in the IEEE 802.11aj wireless link.
