ABSTRACT
High-speed monolithic integrated circuits (ICs) and large-scale ICs (LSIs) are the key components for
multi-gigabit data communication systems and wide-bandwidth radio communication systems. These
systems include backbone networks, intercity communication networks, local area networks, and
Ethernet for data communications, and microwave and millimeter-wave mobile networks, fixed wireless
access (FWA), and intelligent transport systems (ITS) for radio communications. As applications of the
SiGe HBT and BiCMOS technologies described in Chapter 3.7, an IC chipset and LSIs for 40-Gb/s
optical-fiber links, a single-chip 10-Gb/s transceiver LSI, frequency-divider ICs, a 5.8-GHz electronic-
toll-collection (ETC) transceiver IC, and other ICs that are applicable to optical transmission and
microwave/millimeter-wave wireless communication systems have been implemented.
