Feedback Linearization of RF Power Amplifiers

Research activity in the area of radio-frequency (RF) circuit design has surged in the last decade in direct response to the enormous market demand for inexpensive, portable, high data rate wireless transceivers. Our expectations for such transceivers, such as cellular phones, rise as they become seemingly ubiquitous. Once, the simple fact of a fairly reliable wireless voice connection was sufficient and even exciting. Now, crystal-clear voice with no lapses in coverage is actively sought, together with the capability to act as a web portal and even a digital assistant. All of this must be accomplished by a device that is cheap enough to be virtually given away, small enough to justify the claim of portability, and frugal enough with power demands to last a long time on a
single battery charge.
