RF Passive Network Design and Synthesis for Mobile Communications - Volume 1

RF Passive Network Design and Synthesis for Mobile Communications, Volume 1, provides a comprehensive design reference for microwave and RF engineers, bridging a critical gap in the literature with detailed, closed-form analytic design equations for passive network components used in mobile RF front-end design. Distilling decades of experience from RF veteran Peter Wright, this guide focuses on real-world applicability, emphasizes intuitive design tradeoffs and powerful parametric modeling techniques. These methods allow engineers to explore innovative architectures and optimize performance before investing time in complex EM simulation.

Gain an understanding of unique network topologies, with unmatched detail in evaluating high-performance RF components such as couplers, combiners, splitters, and passive matching networks. Leveraging widely accessible tools like Excel, its analytic approach enables fast iteration and provides deep insight into the behavior of RF circuits. With over 650 illustrations, 750 equations, and extensive practical commentary, the book teaches how to model parasitics, design efficient lumped-element networks, and synthesize components that meet demanding performance targets across real-world operating conditions.

This is an indispensable reference for circuit designers, microwave engineers, and RF engineers working with mobile communications modules, power amplifiers, and integrated passive networks. The book offers foundational theory and actionable strategies that solve today’s toughest RF challenges, such as designing compact PA modules and developing next-gen mobile architectures. It helps professionals' model parasitics, synthesize components, and optimize performance, saving significant time and resources in the design process.
