Download or read book A Revolutionary High Efficiency Class F MMIC Amplifier at Ka -band written by Michel Ann Reece and published by . This book was released on 2003 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highly efficient, compact solid-state power amplifier (SSPA) MMICs are required for today's expanding satellite communication applications at Ka-band frequencies. The need for higher data rates, reduced cost, and submicron sizes makes SSPA technologies at Ka-band very attractive. A technique that can be employed to realize high efficiency operation of power amplifiers at microwave frequencies is to employ a Class F amplifier configuration. In order to obtain Class F performance, the output circuit is tuned to pass the fundamental, short (suppress) the second (even) harmonics, and provide an open to the third (odd) harmonics. Thus, providing theoretically an efficiency of 100%. However, at microwave frequencies, transistors are far from ideal. Accurate models are needed to predict the transistor's exotic performance in a circuit. Artificial neural network (ANN) models are a choice alternative for MMIC circuit designers to implement. ANNs have the capability to learn generalize patterns in data and model high linearities. Recently, research has been done that has proved that Knowledge-based Neural Networks (KBNN) are capable of modeling a transistor's small-signal and large-signal characteristics and are quite attractive for implementation in CAD packages. This research employs the use of Class F matching techniques in several prototype single-stage amplifier designs in order to achieve improved efficiency performance at Ka-band frequencies. In addition, Class F MMIC amplifier designs at C-band are also discussed to verify the feasibility of approach. Advanced knowledge-based neural network modeling techniques are implemented for a 300um device in a .25um GaAs PHEMT technology. A KBNN model extraction methodology is derived and integration into a commercial computer-aided (CAD) tool is discussed. A design methodology is developed and utilized to achieve record measured performance of 62% Power-Added-Efficiency at 31 GHz with a gain of 8.7dB and an output power of 18.3dBm. A secondary purpose of this research discusses the impact of the implementation of knowledge-based neural network modeling technique to the design process. -- Abstract.

This book was released on 1969 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The expansion of telecommunication services into the millimeter wave region prompts a careful look at the limitations of the atmosphere that can give rise to severe signal degradations. In Part I the loss and scatter mechanisms in the 10- to 40- GHz range are examined. It is concluded that there is a need for further theoretical and experimental work on the atmospheric propagation properties in order to support the engineering efforts in designing reliable, useful systems. In Part II the discussions are extended to the 40- to 75 -GHz region where absorption by oxygen dominates. In this region, communication through the atmosphere is not practical; however, the oxygen absorption has a great potential for remote sensing of atmospheric variables, and for special (short-range communication) applications. Unsolved problems of the propagation medium are discussed as a basis for formulating proposals; and the objectives of an experimental program for studying oxygen dispersion and absorption are given.

Download or read book The Physics of Semiconductors written by Marius Grundmann and published by Springer Nature. This book was released on 2021-03-06 with total page 905 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 4th edition of this highly successful textbook features copious material for a complete upper-level undergraduate or graduate course, guiding readers to the point where they can choose a specialized topic and begin supervised research. The textbook provides an integrated approach beginning from the essential principles of solid-state and semiconductor physics to their use in various classic and modern semiconductor devices for applications in electronics and photonics. The text highlights many practical aspects of semiconductors: alloys, strain, heterostructures, nanostructures, amorphous semiconductors, and noise, which are essential aspects of modern semiconductor research but often omitted in other textbooks. This textbook also covers advanced topics, such as Bragg mirrors, resonators, polarized and magnetic semiconductors, nanowires, quantum dots, multi-junction solar cells, thin film transistors, and transparent conductive oxides. The 4th edition includes many updates and chapters on 2D materials and aspects of topology. The text derives explicit formulas for many results to facilitate a better understanding of the topics. Having evolved from a highly regarded two-semester course on the topic, The Physics of Semiconductors requires little or no prior knowledge of solid-state physics. More than 2100 references guide the reader to historic and current literature including original papers, review articles and topical books, providing a go-to point of reference for experienced researchers as well.
