Methods for constructing microwave frequency synthesizers are described. The definition of a frequency synthesizer, its main parameters and characteristics are given. The main methods of frequency synthesis and components of frequency synthesizers, including various types of oscillators, are considered. Various architectural solutions are presented to improve the quality of generated signal. The book is illustrated with numerous examples aimed at intuitive understanding of the nature of microwave generation and synthesis effects and their use in practice. A step-by-step process of developing a frequency synthesizer is described using the example of a common PLL. Detailed block diagrams of a number of frequency synthesizers are given. The issues of expanding their functionality are considered. Methods for measuring the main characteristics, principles and features of their implementation are briefly described.
The book can be useful for engineers of all skill levels as a guide to design and measurements in the field of signal generation and frequency synthesis, as well as researchers, technical consultants, graduate students and students of relevant radio engineering specialties.
