Book excerpt: This authoritative book gives you new perspective on the RF and analog hardware and systems design aspects of software defined radio. It delves into the architecture of transmitters and receivers that make software-defined radio a reality. Covering both the practical aspects and underpinnings of these architectures, the book details all key RF and analog baseband components and sub-systems, from the converters that interface with DSPs and ASICs through to the duplexer feeding the antenna. It enables you to select the right technique for any application by providing alternatives for implementing the main system components.
