MM-wave transceivers using SiGe HBT technology

Abstract

High-speed wireless technology has been evolving with roughly 2x speed improvements every 18 months. Currently the wireless local-area network (WLAN) and wireless personal-area network (WPAN) spaces are developing new standards to increase wireless speeds beyond the 10-54Mbps achieved in the first and second generation IEEE wireless network standards. Challenging issues which must be addressed in these new high-rate standards include FCC restrictions on maximum radiated power and power spectral density, bandwidth limitations in the available 2.4 and 5GHz ISM bands, and cost and power required to support the high date rates in portable devices. This paper discusses the realization of a mm-wave transceiver in advanced SiGe HBT technology for application in high-speed mm-wave wireless systems. A low-power, integrated 60GHz transceiver opens up the potential for economical high-speed wireless systems which can take advantage of >5GHz of unlicensed spectrum available in the 60GHz ISM band. © 2004 IEEE.
