Design of Linear RF Outphasing Power Amplifiers

Download or read book Design of Linear RF Outphasing Power Amplifiers written by Xuejun Zhang and published by Artech House. This book was released on 2003 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes the outphasing approach to amplifier linearization that uses power-combining techniques to create a linear output waveform from two nonlinear input sources, and presents recent advances in resolving the limitations caused by the strict matching requirements between the two amplifiers and the microwave power wasted in the power-combing network. The authors discuss the linearity performance of outphasing amplifier systems, correction schemes based on training vectors, and power recycling in outphasing amplifiers. Zhang is an engineer with Qualcomm, while Larson and Asbeck are affiliated with the University of California, San Diego. Annotation (c)2003 Book News, Inc., Portland, OR (booknews.com).
