What is Polar Transmitter about?

This paper discusses the design issues of highly efficient and monolithic wideband RF polar transmitters, especially the ones that use the envelope-tracking technique. A design prototype of a polar transmitter using ET and a monolithic SiGe PA that passed the stringent low-band EDGE transmit mask will be given. Further investigations on how to solve the technical challenges to successfully implement linear and high-efficiency ET-based polar transmitter for broadband wireless applications are also discussed.
