Distortion in RF Power Amplifiers de Joel Vuolevi

Distortion in RF Power Amplifiers: Artech House Microwave Library

Autor Joel Vuolevi, Timo Rahkonen
en Limba Engleză Hardback – 31 ian 2003
Here is a thorough treatment of distortion in RF power amplifiers. This unique resource offers expert guidance in designing easily linearizable systems that have low memory effects. It offers you a detailed understanding of how the matching impedances of a power amplifier and other RF circuits can be tuned to minimize overall distortion. What’s more, you see how to build models that can be used for distortion simulations.
