RF circuit design is now more important than ever as we find ourselves in an increasingly wireless world. Radio is the backbone of today’s wireless industry with protocols such as Bluetooth, Wi-Fi, WiMax, and ZigBee. Most, if not all, mobile devices have an RF component and this book tells the reader how to design and integrate that component in a very practical fashion. This book has been updated to include today's integrated circuit (IC) and system-level design issues as well as keeping its classic "wire lead" material. Design concepts and tools includes:The Basics: Wires, Resistors, Capacitors, InductorsResonant Circuits: Resonance, Insertion Loss Filter Design: High-pass, Bandpass, Band-rejectionImpedance Matching: The L Network, Smith Charts, Software Design ToolsTransistors: Materials, Y Parameters, S ParametersSmall Signal RF Amplifier: Transistor Biasing, Y Parameters, S ParametersRF Power Amplifiers: Automatic Shutdown Circuitry , Broadband Transformers, Practical Winding HintsRF Front-End: Architectures, Software-Defined Radios, ADC’s EffectsRF Design Tools: Languages, Flow, Modeling
