Integrated millimeter-wave transceiver concepts and technologies for wireless multi-Gbps communication

This paper provides an overview of millimeter-wave transceiver frontend concepts and realizations for wireless multi-Gbps communication applications. Different state-of-the-art heterodyne and direct-conversion frontend implementations in silicon-germanium technology (SiGe) with their related applications are presented. These include highly compact embedded transceiver solutions featuring novel antenna-in-package concepts for low-cost short-range indoor 60 GHz broadband Wi-Fi/WLAN and WPAN access points. Furthermore, highly integrated multi-band transmitter and receiver chipsets in the 70/80GHz E-Band as well as the complete 50–100 GHz frequency range for outdoor wireless backhaul point-to-point communication links and fixed local area network extension are outlined.
