Modern RF radios developed for broadband services requires non-linear RF front ends which handle wide bandwidth, operate linearly and are power efficient.

This course will introduce microwave/RF engineers and researchers to modern large-signal characterization, design and linearization techniques which have been developed to address these challenges.
