How to get it?

Information in its various forms is always finding its prominent place at the center of our daily lives. Consequently, many consumers demand access to information on global events, be it accessible via a mobile telephone, a computer network or a television or radio. All of these technologies would not be conceivable without semiconductors, whereby the significance of high-frequency engineering has exploded in the last few decades, therefore making the know-how and technology in this area ever more important.

Infineon Technologies has cooperated with the Vienna University of Technology and the software development company Epina GmbH to provide an electronic manual which is based on the ideas of Gerhard Lohninger, the head of the development division for discrete semiconductors of Infineon Technologies. This electronic book offers on the one hand a summary and a reference book for engineers and technicians, but also alternatively an entry into the world of modern, high-frequency semiconductor technology to managers, students and the technically interested layman. The new edition offers additional material on the electromagnetic spectrum, the Maxwell equations and the corresponding mathematics, the fundamentals of motors and power generators, the principles of antennas and the basics of power management products.

The goal of this eBook is to link the discrete semiconductors of Infineon with the appropriate fundamentals in the areas of technology, system engineering, applications and historical development and to present this to the readers in an easily understandable form using animations and simple programs. Furthermore, an integrated short-form catalog about the products provides an overview and references for selecting components for concrete applications. The eBook has a volume of approximately 205,000 words, about 1200 illustrations and 30 interactive examples.

The term "Discrete Semiconductor" or simply the abbreviation "Discretes" is normally used synonymously with chips packed into small packages for portable radio, consumer and automotive applications. This category mainly consists of silicon components like diodes and transistors in the low- and high-frequency range. In addition, Si-MMIC building blocks, HiPACs, MEMS and HiRel devices belong to this group. Futhermore, Tuner-ICs and their applications in the consumer area serve as a system platform for RF-Diodes and RF-MOS transistors and are therefore included. "Discrete Components" are characterized by a broad application scope, a large possible frequency range, as well as high flexibility and the use of state-of-the-art technologies combined with the most modern packaging technologies.

This manual differs from conventional, printed books also in the technology of accessing material. It is intentionally not based on a printed version and is an attempt to try out new paths in accessing electronic information. Specifically with technically oriented books, an electronic version offers greater advantages, since classical reading (and learning) from paper is receding and the interactivity and the fast access to information is becoming ever increasingly important. Here, this book goes new directions where, on the one hand, it offers interactive examples embedded into the text, however it alternatively also maintains significant value as a reference source using sophisticated navigation options.

This approach was made possible by using a modern and proven development system for electronic books, Coimbra, from the company Epina, which provides all of the important tools needed for the production of electronic books. Details about Coimbra can be viewed at the Web page:
