Fully integrated millimeter-wave transceiver ICs using 65nm CMOS technology and on-board antenna for highspeed/short-range wireless communication system are described. To realize high-speed and low power consumption for a mobile application, a simple transceiver architecture with non-coherent amplitude shift keying (ASK) modulation method is adopted. The transceiver ICs are flip-chip bonded on boards and connected with on-board antenna for a simple and low cost transceiver system. The developed transceiver system module demonstrates 5Gbps/3.8Gbps at wireless communication range of 5mm/10mm and power consumption of 79.6mW with a carrier frequency of 71GHz. To our best knowledge, this is the first report of a millimeter-wave, above 60GHz, CMOS transceiver module with on-board antenna for a highspeed/short-range wireless communication system.
