An introduction to RF propagation that spans all wirelessapplications This book provides readers with a solid understanding of theconcepts involved in the propagation of electromagnetic waves andof the commonly used modeling techniques. While many books cover RFpropagation, most are geared to cellular telephone systems and,therefore, are limited in scope. This title is comprehensive-ittreats the growing number of wireless applications that range wellbeyond the mobile telecommunications industry, including radar andsatellite communications. The author's straightforward, clear style makes it easy for readersto gain the necessary background in electromagnetics, communicationtheory, and probability, so they can advance to propagation modelsfor near-earth, indoor, and earth-space propagation. Criticaltopics that readers would otherwise have to search a number ofresources to find are included: * RF safety chapter provides a concise presentation of FCCrecommendations, including application examples, and preparesreaders to work with real-world propagating systems * Antenna chapter provides an introduction to a wide variety ofantennas and techniques for antenna analysis, including a detailedtreatment of antenna polarization and axial ratio; the chaptercontains a set of curves that permit readers to estimatepolarization loss due to axial ratio mismatch between transmittingand receiving antennas without performing detailedcalculations * Atmospheric effects chapter provides curves of typicalatmospheric loss, so that expected loss can be determinedeasily * Rain attenuation chapter features a summary of how to apply theITU and Crane rain models * Satellite communication chapter provides the details ofearth-space propagation analysis including rain attenuation,atmospheric absorption, path length determination and noisetemperature determination Examples of widely used models provide all the details andinformation needed to allow readers to apply the models withconfidence. References, provided throughout the book, enablereaders to explore particular topics in greater depth.Additionally, an accompanying Wiley ftp site provides supportingMathCad files for select figures in the book. With its emphasis on fundamentals, detailed examples, andcomprehensive coverage of models and applications, this is anexcellent text for upper-level undergraduate or graduate students,or for the practicing engineer who needs to develop anunderstanding of propagation phenomena.

View: 355

The ultimate practical resource for today's RF system design professionals Radio frequency components and circuits form the backbone of today's mobile and satellite communications networks. Consequently, both practicing and aspiring industry professionals need to be able to solve ever more complex problems of RF design. Blending theoretical rigor with a wealth of practical expertise, Practical RF System Design addresses a variety of complex, real-world problems that system engineers are likely to encounter in today's burgeoning communications industry with solutions that are not easily available in the existing literature. The author, an expert in the field of RF module and system design, provides powerful techniques for analyzing real RF systems, with emphasis on some that are currently not well understood. Combining theoretical results and models with examples, he challenges readers to address such practical issues as: * How standing wave ratio affects system gain * How noise on a local oscillator will affect receiver noise figure and desensitization * How to determine the dynamic range of a cascade from module specifications * How phase noise affects system performance and where it comes from * How intermodulation products (IMs) predictably change with signal amplitude, and why they sometimes change differently An essential resource for today's RF system engineers, the text covers important topics in the areas of system noise and nonlinearity, frequency conversion, and phase noise. Along with a wealth of practical examples using MATLAB(r) and Excel, spreadsheets are available for download from an FTP Web site to help readers apply the methods outlined in this important resource.
