Feedforward Linear Power Amplifiers

Coinciding with the evolution of new standards for mobile communications systems and wireless multimedia services, this text provides an introduction and analysis of linear feedforward power amplifiers. It guides the reader through the feedforward design process, starting with the initial system specifications and continuing with a detailed look at the practical implementation of feedforward. The linearity and bandwidth demands on power amplifiers are explained in relation to the use of spectrally efficient linear modulation schemes and wide operating bandwidths for high data rate applications such as multimedia and Internet. The book includes numerous examples and analyses the advantages and disadvantages of different implementations, radio standards and system configurations. Future design trends are discussed and a review of alternative linearization techniques is also included.
