Download or read book RF-MEMS Switches Designed for High-Performance Uniplanar Microwave and Mm-Wave Circuits written by Lluis Pradell. This book was released on 2018. Available in PDF, EPUB and Kindle. Book excerpt: Radio frequency microelectromechanical system (RF-MEMS) switches have demonstrated superior electrical performance (lower loss and higher isolation) compared to semiconductor-based devices to implement reconfigurable microwave and millimeter (mm)-wave circuits. In this chapter, electrostatically actuated RF-MEMS switch configurations that can be easily integrated in uniplanar circuits are presented. The design procedure and fabrication process of RF-MEMS switch topologies able to control the propagating modes of multimodal uniplanar structures (those based on a combination of coplanar waveguide (CPW), coplanar stripline (CPS), and slotline) will be described in detail. Generalized electrical (multimodal) and mechanical models will be presented and applied to the switch design and simulation. The switch-simulated results are compared to measurements, confirming the expected performances. Using an integrated RF-MEMS surface micromachining process, high-performance multimodal reconfigurable circuits, such as phase switches and filters, are developed with the proposed switch configurations. The design and optimization of these circuits are discussed and the simulated results compared to measurements.

Book excerpt: MEMS by becoming a part of various applications ranging from smartphones to automobiles has become an integral part of our everyday life. MEMS is building synergy between previously unrelated fields such as biology, microelectronics and communications, to improve the quality of human life. The sensors in MEMS gather information from the surrounding, which is then processed by the electronics for decision-making to control the environment. MEMS offers opportunities to miniaturize devices, integrate them with electronics and realize cost savings through batch fabrication. MEMS technology has enhanced many important applications in domains such as consumer electronics, biotechnology and communication and it holds great promise for continued contributions in the future. This book focuses on understanding the design, development and various applications of MEMS sensors.
