Available in PDF, EPUB and Kindle. Book excerpt: In order to incorporate the RF MEMS technology with the 3D MMICs technology, a novel RF MEMS switch was designed and implemented in a 3D MMIC circuit environment. RF MEMS switches possess many advantages compared to traditional solid-state switches, such as high electromechanical isolation, and ultra-low power consumption. The novelty of this switch was that it was based on low temperature processing techniques. Design equations for a shielded coplanar waveguide were derived for the switch. Traditional lumped element capacitor model and this newly developed distributed transmission line models were compared against measured data to verify their validity. While measurement results show good agreement with both models, the distributed model consistently demonstrated better match than its lumped element counterpart. Test and measurement results showed that a typical RF MEMS switch was capable of delivering less than 0.2dB insertion loss and more than 14.1dB isolation between input and output ports at X-band (8GHz-12GHz). This RF MEMS switch required only 12V actuation voltage while it was capable of handling 2.88W RF power before "hot-switching" occurs. Hysteretic phenomenon of RF MEMS switches was observed; release voltage threshold was found to be around 2V 4V, much lower than the one required for pulling down the structure. Switching speeds of RF MEMS switches with different beam strength were measured using a novel experimental setup utilizing couplers as bias networks. The fastest switches demonstrated maximum switching speed of 3.571 kHz and more than 10,800,000 life cycles. As the application of RF MEMS switches, a 4-bit digital phase shifter was designed and fabricated. 180ʻ bit and 90ʻ bits were realized using reflection type phase shifters, while the 45ʻ and 22.5ʻ bits were achieved using loaded-line type phase shifters. A novel reflection type phase shifter loaded with multiple switch pairs was developed and was capable of delivering multiple phase shift angles within one circuit stage. Phase shifter measurement results were consistent with simulated results.

Download or read book Introduction to Microsystem Packaging Technology written by Yufeng Jin and published by CRC Press. This book was released on 2017-12-19 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The multi-billion-dollar microsystem packaging business continues to play an increasingly important technical role in today’s information industry. The packaging process—including design and manufacturing technologies—is the technical foundation upon which function chips are updated for use in application systems, and it is an important guarantee of the continued growth of technical content and value of information systems. Introduction to Microsystem Packaging Technology details the latest advances in this vital area, which involves microelectronics, optoelectronics, RF and wireless, MEMS, and related packaging and assembling technologies. It is purposefully written so that each chapter is relatively independent and the book systematically presents the widest possible overview of packaging knowledge. Elucidates the evolving world of packaging technologies for manufacturing The authors begin by introducing the fundamentals, history, and technical challenges of microsystems. Addressing an array of design techniques for packaging and integration, they cover substrate and interconnection technologies, examples of device- and system-level packaging, and various MEMS packaging techniques. The book also discusses module assembly and optoelectronic packaging, reliability methodologies and analysis, and prospects for the evolution and future applications of microsystems packaging and associated environmental protection. With its research examples and targeted reference questions and answers to reinforce understanding, this text is ideal for researchers, engineers, and students involved in microelectronics and MEMS. It is also useful to those who are not directly engaged in packaging but require a solid understanding of the field and its associated technologies.
Book Synopsis Development of Monolithic SiGe and Packaged RF MEMS High-linearity Five-bit High-low Pass Phase Shifters for SoC X-band T/R Modules by : Matthew A. Morton
Download or read book Development of Monolithic SiGe and Packaged RF MEMS High-linearity Five-bit High-low Pass Phase Shifters for SoC X-band T/R Modules written by Matthew A. Morton and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive study of the High-pass/Low-pass topology has been performed, increasing the understanding of error sources arising from bit layout issues and fabrication tolerances. This included a detailed analysis of error sources in monolithic microwave phase shifters due to device size limitations, inductor parasitics, loading effects, and non-ideal switches. Each component utilized in the implementation of a monolithic high-low pass phase shifter was analyzed, with its influence on phase behavior shown in detail. An emphasis was placed on the net impact on absolute phase variation, which is critical to the system performance of a phased array radar system. The design of the individual phase shifter filter sections, and the influence of bit ordering on overall performance was also addressed. A variety of X-band four- and five-bit phase shifters were fabricated in a 200 GHz SiGe HBT BiCMOS technology platform, and further served to validate the analysis and design methodology. The SiGe phase shifter can be successfully incorporated into a single-chip T/R module forming a system-on-a-chip (SoC). Reduction in the physical size of transmission lines was shown to be a possibility with spinel magnetic nanoparticle films. The signal transmission properties of phase lines treated with nanoparticle thin films were examined, showing the potential for significant size reduction in both delay line and High-pass/Low-pass phase topologies. Wide-band, low-loss, and near-hermetic packaging techniques for RF MEMS devices were presented. A thermal compression bonding technique compatible with standard IC fabrication techniques was shown, that uses a low temperature thermal compression bonding method that avoids plastic deformations of the MEMS membrane. Ultimately, a system-on-a-package (SoP) approach was demonstrated that utilized packaged RF MEMS switches to maintain the performance of the SiGe phase shifter with much lower loss. The extremely competitive performance of the MEMS-based High-pass/Low-pass phase shifter, despite the lack of the extensive toolkits and commercial fabrication facilities employed with the active-based SiGe phase shifters, confirms both the effectiveness of the detailed phase error analysis presented in this work and the robust nature of the High-pass/Low-pass topology.
