Book Description
Microelectromechanical systems (MEMS) refer to a collection of micro-sensors and actuators, which can react to environmental change under micro- circuit control. The integration of MEMS into traditional Radio Frequency (RF) circuits has resulted in systems with superior performance levels and lower manufacturing costs. The incorporation of MEMS based fabrication technologies into micro and millimeter wave systems offers viable routes to ICs with MEMS actuators, antennas, switches and transmission lines. The resultant systems operate with an increased bandwidth and increased radiation efficiency and have considerable scope for implementation within the expanding area of wireless personal communication devices. This text provides leading edge coverage of this increasingly important area and highlights the overlapping information requirements of the RF and MEMS research and development communities. * Provides an introduction to micromachining techniques and their use in the fabrication of micro switches, capacitors and inductors * Includes coverage of MEMS devices for wireless and Bluetooth enabled systems Essential reading for RF Circuit design practitioners and researchers requiring an introduction to MEMS technologies, as well as practitioners and researchers in MEMS and silicon technology requiring an introduction to RF circuit design.

Book Description
In this research, a unique fabrication technology to build high-aspect-ratio via interconnects in 3D MMIC multilayer integration was developed from a combination of microelectronic and traditional MEMS microfabrication technologies. Based on these techniques, a set of test structures have been successfully fabricated to facilitate the vertical interconnect characterization. Fully cured polyimide thin films possess favorable electric and mechanical properties for the 3D MMIC applications. Using quarter wavelength T-junction resonator structure, polyimide was characterized for its microwave properties. High-frequency characterization of polyimide thin films was obtained in a wide frequency range. Experimental results have shown the feasibility of this method. In order to correctly evaluate the conductor loss in thin planar transmission lines, a modified conductor loss model was derived from conventional Wheeler's incremental inductance rule to account for the field penetration as the physical strip thickness approaches the skin depth or even smaller. The closed-form formulas or simplified equations have been developed for microstrip and stripline with wide strip cases, and for general coplanar waveguide including SCPWG line. Meanwhile, experimental results verified the validity of the modified conductor loss model in evaluating the losses in thin transmission lines. It has been shown that as the conductor thickness becomes approximately greater than four times of the skin depth, both conventional Wheeler's rule and its modified model agree with each other very well on the conductor loss estimation. Experimental results have revealed that at RF frequency, e.g. X band (8-12 GHz), the vertical interconnection discontinuities may contribute significantly to the insertion loss and the phase change. With the advanced conductor loss models for evaluating the characteristics in the test structures, lumped-element equivalent circuit models can be derived from the via module measurement results. These models are of great practical importance in a complex circuit design.

Book Description
This book presents a step-by-step discussion of the 3D integration approach for the development of compact system-on-package (SOP) front-ends.Various examples of fully-integrated passive building blocks (cavity/microstip filters, duplexers, antennas), as well as a multilayer ceramic (LTCC) V-band transceiver front-end midule demonstrate the revolutionary effects of this approach in RF/Wireless packaging and multifunctional miniaturization. Designs covered are based on novel ideas and are presented for the first time for millimeterwave (60GHz) ultrabroadband wireless modules.
