The book contains eighteen Chapters. Chapter 1 is the introductory one and gives the brief description and structure of common radiocommunication system, description of signal processing in some parts of the system, and importance of radio waves in wireless telecommunications. Chapters 2, 3, 4 and 5 depict the basic wireless communications circuits. Chapter 2 covers the active element characteristics and its equivalent models,RF caracteristic of transistors and diodes.In this Chapter the transmision line caracteristics is introducts, with using the Smith cart in RF circuits design .Chapter 3 gives the selective amplifiers for low signals, which is the basic part of every radio system. Chapter 4 and 5 include the power amplifiers in the class A, B, C, D and E and the method of their matching.
Chapter 6 is dedicated to high frequency oscillators, with special attention to voltage-controlled oscillators (VCO). Chapter 7 covers the PLL loop with all aspect of its usage. Chapter 7 includes analog, hybrid, fully digital and software PLL. Chapter 8 is dedicated to analog multipliers.
Chapters 9 and 10 are dedicated to AM and FM modulation and modulators, and Chapter 11 gives the special look to radio receivers types. Chapters 12, 13, 14 and 15 cover the main blocks of radio receiver, as AM and FM detectors, frequency mixers, etc.
Chapters 16 and 17 are dedicated to radio systems, and Chapter 18 provides a review of radio waves propagation.
Book covers the material for 4 or 5 one-semester courses, for graduate or postgraduate students. This book, though written for students and postgraduates, can be useful to all those engineers and scientists who wish to practice in the field of radioengineering.
