RF Circuit Design
This book targets the four most difficult skills facing RF/RFIC designers today: impedance matching, RF/AC grounding, Six Sigma design, and RFIC technology. Unlike most books on the market, it presents readers with practical engineering design examples to explore how they're used to solve ever more complex problems. The content is divided into three key parts:
Individual RF block circuit design
Basic RF circuit design skills
RF system engineering
The author assumes a fundamental background in RF circuit design theory, and the goal of the book is to enable readers to master the correct methodology. The book includes treatment of special circuit topologies and introduces some useful schemes for simulation and layout.
This is a must-read for RF/RFIC circuit design engineers, system designers working with communication systems, and graduates and researchers in related fields.
