تحریف در تقویت‌کننده‌های قدرت RF (کتابخانه مایکروویو آرتک هاوس)

A treatment of distortion in RF power amplifiers. It seeks to offer guidance on designing easily linearizable systems that have low memory effects. The reader is offered a detailed understanding of how the matching impedances of a power amplifier and other RF circuits can be tuned to minimize overall distortion. It also demonstrates how to build models that can be used for distortion simulations.The measurement methodology should enable the reader to gauge the amplitude and phase of distortion components and recognize memory effects. The volume explains that by killing memory effects, it is possible to use simple linearizers, such as analogue predistortion, and still achieve sufficient performance. It presents a distortion analysis technique that allows you to repeat the analysis with other amplifier structures. With over 120 equations and more than 110 illustrations, this practical reference seeks to provide the assistance necessary to create amplifiers suitable for linear transmitters, and offers views of semiconductor modelling. Annotation For microwave engineers and designers whose work involves RF (radio frequency) power amplifiers, minimizing distortion is a major issue that must be addressed. Here is a thorough treatment of distortion in RF power amplifiers for professionals in the field. This unique resource offers practitioners a detailed understanding of how the matching impedances of a power amplifier and other RF circuits can be tuned to reduce overall distortion. What's more, the book shows how to build models that can be used for distortion simulation. It covers new circuit design techniques that increase the performance of linearization

reviews The Most Common Linearization Techniques And The Different Types Of Memory Effects They Cause In Rf Power Amplifiers, Then Presents Three Techniques For Canceling Those Memory Effects: Envelope Filtering, Impedance Optimization, And Envelope Injection. Along The Way, The Finnish Authors Demonstrate How To Calculate Distortion Of A Common Emitter Amplifier Using Volterra Analysis, And How To Extract The Parameters Of Volterra Models For Rf Power Transistors From Measured Data. The Book Is Intended For Practicing Microwave And Electrical Engineers. Annotation (c)2003 Book News, Inc., Portland, Or
