Full Description


MEMS (microelectromechanical systems) for RF (radio frequency) / wireless applications is the technological engine enabling the use of even smaller, more sophisticated wireless products than before. This book addresses the design of RF MEMS-based circuits for use in high-performance wireless systems. It aims to: enable professionals to understand the realm of applications in RF MEMS technology; become knowledgeable of the wide variety and performance levels of RF MEMS devices; and design the architecture of wireless systems to achieve greater system performance with lower power requirements. This book is aimed at practising wireless and microwave engineers and managers, as well as electrical engineering professors and students.
