Abstract
This course reviews key RF transmitter power amplifier linearization issues. The underlying power amplifier nonlinearity problem, that of the competing requirements of power amplifier efficiency and linear signal transmission paths for bandwidth efficient, modulation-complex signals, is presented, together with the linearization solution. Modern linearization schemes and where linearization research, and technology, is headed is addressed.
