摘要：
This paper describes advantages and peculiarities of class E power amplifier when used in a polar transmitter system. Basic principles about class E and information about different nonlinearities are given. Also, modifying transistor model to switch use is discussed briefly. A 1 GHz, 0.5 W class E power amplifier was implemented for a polar transmitter. Differences between transmitter systems are mentioned and measurements of a total transmitter system performance are presented.
