Radio frequency integrated circuits (RFICs) are an important part of today's wireless communications devices and infrastructure. An RFIC design approach involving cutting-edge bipolar technologies (GaAs HBT or SiGe HBT) has gained popularity among engineers due to its ability to maximize performance; however, it has been largely ignored in professional reference books. This book fills the gap, offering practitioners a detailed treatment of this increasingly important topic. From discussions of key applications (Bluetooth, UWB, GPS, WiMax) and architectures...to in-depth coverage of fabrication technologies and amplifier design...to a look at performance tradeoffs and production costs, this book arms engineers with complete design know-how for their challenging work in the field.
