Download or read book Systems Level Packaging for Millimeter Wave Transceivers written by Mladen Božanić and published by Springer. This book was released on 2019-03-26 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a system-level approach to making packaging decisions for millimeter-wave transceivers. In electronics, the packaging forms a bridge between the integrated circuit or individual device and the rest of the electronic system, encompassing all technologies between the two. To be able to make well-founded packaging decisions, researchers need to understand a broad range of aspects, including: concepts of transmission bands, antennas and propagation, integrated and discrete package substrates, materials and technologies, interconnects, passive and active components, as well as the advantages and disadvantages of various packages and packaging approaches, and package-level modeling and simulation. Packaging also needs to be considered in terms of system-level testing, as well as associated testing and production costs, and reducing costs. This peer-reviewed work contributes to the extant scholarly literature by addressing the aforementioned concepts and applying them to the context of the millimeter-wave regime and the unique opportunities that this transmission approach offers.

Download or read book Millimeter Wave Wireless Power Transfer Systems for the Internet of Things written by Med Nariman and published by . This book was released on 2016 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Internet of Things (IoT) would add computational power to a plethora of ordinary objects. Potential applications are vast and vary in terms of maturity from sensors tracking energy usage to smart wearables and many more futuristic applications. A challenge shared by many of such small devices, in the order of a few centimeters in length and width, is battery and power. Cost, size, weight, and lifetime of the battery motivate alternative methods for providing energy to such devices. A practical Wireless Power Transfer (WPT) system which can power battery-less and charge coil-free smart everyday-objects has a tremendous potential to address this demand. In this work we offer a reliable solution. The 60-GHz WPT system that is built in this project can be employed by any smart device which can be placed at a reasonably close distance to its power transmitter, without the alignment and proximity challenges which are associated with the magnetic charging solutions. The leading applications to benefit enormously from this new 60-GHz WPT technology are miniature IoT devices, smart charge cards, business cards and IDs, smart posters, sensor fusion, and wireless flash memories.In this work, the first reported full-system 60-GHz WPT solution which can power battery-less and charge coil-free compact smart devices is presented. The system is fabricated in a 40-nm digital CMOS process and an inexpensive 500-mum CCL-HL832MG antenna packaging material. The rectenna (RX) of this 60-GHz WPT system consists of a grid antenna with a measured gain of 10.7 dBi, integrated with a tuned complementary cross-coupled oscillator-like rectifier. It harvests DC power at a rate of 1 mW with a 28.2% RF-to-DC Power Conversion Efficiency (PCE). This PCE rate is significantly higher than the prior art and reaches 32.8% for 1.4 mA output current. A novel theoretical analysis of the unique rectifier circuitry is presented which helps formulating all key specifications and identifying the design trade-offs. We present a cascode version of the energy harvester that produces higher DC output voltage and higher PCE in low current regime. The theoretical analysis and the results of the measurement for that harvester is also presented. The transmitter (TX) is equipped with a quad-core power amplifier which produces a total saturated output power (Psat) of 24.6 dBm, which is the highest reported power delivery in digital CMOS technology at mm-wave bands. The TX peak PAE is 9.4%. The quad-core PA performs a 4 x 8-way differential power combining and implements a binary-tree architecture by using power-splitting transformers which perform intra-stage matching too. The designed 2 x 2 grid array antenna helps the TX produce a peak EIRP level of 35.3 dBm. The coupling between the TX and RX antennas within 4 cm spacing is between -18.9 and -17.4dB. The results of full-system characterizations of the WPT solution and the measurements data of the individually-fabricated grid antennas, harvester, transmitter, and all building blocks are reported. Programmability in the input polarities of the quad-core PA offers output power control and beam-steering capabilities to this 60-GHz WPT system. A four-input grid antenna is designed for the TX which in simulation shows an effective 70° beam-steering range in the broadside direction.In order to demonstrate how the design and implementation of all the 60-GHz circuitry has been as successful as they are, the design of the VCOs, quadrature VCOs, PAs, unit-cell devices, pads and calibration circuitry, passive components like inductors, transformers, capacitors, the patch antennas, and the grid array antennas that have been done before the final implementation of the full wireless power transfer system are presented as well and the key design points are specified and explained. The architecture study for the transmitter and the energy harvester are also included in this dissertation since they have been most vital parts of accomplishing the design of the highest transmit power delivery and highest rectenna power conversion efficiency in digital CMOS technology. The 60-GHz WPT system designed for this work can serve miniature sized smart everyday-objects which require milliwatt-level power delivery and work in contact-less and close-proximity distances. The full-system measurement results of the proposed 60-GHz wireless power transfer solution demonstrate the suitability of this mm-wave WPT system for addressing the demand for wireless power of batteryless and coil-free devices with stringent size constraints of new applications, like the IoT.

This book was released on 2017-12-19 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to the ever-increasing global threat of terrorist attacks, the personal screening industry has been growing at a rapid rate. Many methods have been developed for detecting concealed weapons and explosives on the human body. In this important new book, the authors discuss their experiences over the last decade designing and testing microwave and millimetre wave detection and screening systems. It includes examples of actual devices that they have built and tested, along with test results that were obtained in realistic scenarios. The book focuses on the development of non-imaging detection systems, which are similar to radar. These systems do not form a conventional image of the scene and the person(s) being screened. Instead, the sensors detect and analyze the effect that the body, and any concealed objects, has on a transmitted waveform. These systems allow remote detection of both metallic and dielectric devices concealed on the human body in both indoor and outdoor environments. The book discusses a number of sensor types, including active millimetre wave sensors using the direct detection and the heterodyne approach, active microwave sensors for CNR-based object detection, passive millimetre wave sensors, and the role of shielding effects in operating non-imaging MM-wave sensors. The goal of this book is to systemize the test results obtained by the authors, helping specialists to develop improved screening systems in the future. Another goal is to show how the use of non-imaging systems can reduce the cost of the screening process.

Download or read book Broadband mm Wave Sensors for Industrial and Security Applications written by Peter Feil and published by Cuvillier Verlag. This book was released on 2013-01-28 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last 30 years commercial mm-wave technology was mainly driven by the automotive industry. Having started at 24 GHz, the suppliers in Europe are now forced to switch to the 76-81 GHz frequency band due to administrative regulations. As a consequence, great efforts have been done in developing mm-wave components suitable for low cost mass production. Nowadays, chip sets or even single chip frontends are available, mainly based on GaAs or SiGe technology. Even though these devices are intended for automotive sensors, the technology is also available for fields with low volume and even niche applications. The dissertation describes the development of wideband sensors at 79 GHz suited to address many potential applications within different areas like industrial and security sensing.

Download or read book Advanced Materials and Technologies for Micro Nano Devices Sensors and Actuators written by Evgeni Gusev and published by Springer. This book was released on 2010-03-03 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: A NATO Advanced Research Workshop (ARW) entitled “Advanced Materials and Technologies for Micro/Nano Devices, Sensors and Actuators” was held in St. Petersburg, Russia, from June 29 to July 2, 2009. The main goal of the Workshop was to examine (at a fundamental level) the very complex scientific issues that pertain to the use of micro- and nano-electromechanical systems (MEMS and NEMS), devices and technologies in next generation commercial and defen- related applications. Micro- and nano-electromechanical systems represent rather broad and diverse technological areas, such as optical systems (micromirrors, waveguides, optical sensors, integrated subsystems), life sciences and lab equipment (micropumps, membranes, lab-on-chip, membranes, microfluidics), sensors (bio-sensors, chemical sensors, gas-phase sensors, sensors integrated with electronics) and RF applications for signal transmission (variable capacitors, tunable filters and antennas, switches, resonators). From a scientific viewpoint, this is a very multi-disciplinary field, including micro- and nano-mechanics (such as stresses in structural materials), electronic effects (e. g. charge transfer), general electrostatics, materials science, surface chemistry, interface science, (nano)tribology, and optics. It is obvious that in order to overcome the problems surrounding next-generation MEMS/NEMS devices and applications it is necessary to tackle them from different angles: theoreticians need to speak with mechanical engineers, and device engineers and modelers to listen to surface physicists. It was therefore one of the main objectives of the workshop to bring together a multidisciplinary team of distinguished researchers.
