Book Review - Small Signal Microwave Amplifier Design - Microwave Journal February 2001

This book focuses on analytical methods of high frequency amplifier design by determining the characteristics of input and output networks and their subsequent synthesis. The emphasis is on narrowband, small-signal amplifiers at RF and microwave frequencies. Each section includes an example that demonstrates how to apply the technique discussed and additional problems are offered at the end of each chapter. MatLab and Genesys program listings are included. A separate Solutions manual (ISBN 1-884932-09-6) is available separately for $19.

The book begins by reviewing basic concepts of networks and common network parameters. Next, the electrical properties of transmission lines are described using the fundamental theory of propagation. The use of a Smith chart is demonstrated and S-parameters are introduced. Signal propagation, power flow and circuit response are derived using S-parameters.

Next, how to analyze high frequency circuits using S-parameters and the Smith chart is demonstrated. Mapping functions and signal flow graphs are introduced. Several impedance-matching design techniques are shown along with their applications.

The information contained in transistor data sheets is described and amplifiers are designed by determining the desired impedance or reflection coefficient of the transistor input and output circuits. Finally, noise and noise figure are discussed and the definitions are used to modify as a design criterion. The impact of system noise on signal -to-noise-ratio is described.

This book is unusually clear tutorial on small-signal amplifier design that uses the latest circuit analysis and CAD tools in a step-by-step design approach. It is an excellent reference book for RF and microwave designers, as well as a good textbook for engineering students.
