Practical RF Systems Design and Testing for 5G Wireless Communications and Beyond

Combines theoretical foundations with hands-on verification techniques, enabling readers to move seamlessly from concept to implementation As wireless systems advance into the 5G and emerging 6G era, RF engineers face growing complexity in millimeter-wave systems, massive MIMO, intelligent surfaces, and stringent performance verification requirements. This book provides a rigorous, practice-oriented framework that bridges foundational RF theory with real-world implementation. The text delivers a comprehensive, application-focused treatment of the complete RF signal chain, from wireless system fundamentals and transmission lines to essential RF building blocks, including low-noise amplifiers, mixers, filters, synthesizers, oscillators, and power amplifiers. A dedicated chapter addresses high-efficiency power amplifier design, covering Doherty architectures, efficiency enhancement strategies, linearization techniques, and implementation considerations for 5G transmitters. Additional chapters examine receiver architectures, antenna design and measurement, reconfigurable intelligent surfaces (RIS), and analog, digital, and hybrid beamforming techniques that define modern wireless infrastructure. A distinguishing feature of the book is its strong emphasis on RF measurement and compliance. Readers gain practical guidance on RF instrumentation, including VNA calibration, spectrum and signal analyzers, noise figure measurement, and power measurement. Structured Radio Performance Verification (RPV) procedures for 5G NR transmitters and receivers, including over-the-air testing, are presented in a clear, systematic format. The integration of design principles with verification methodology makes the book especially valuable for engineers engaged in research, product development, validation, and manufacturing.
