Abstract(in English) In this paper, a high power and high efficiency partially-impedance matched GaN FET operating at L-band is presented. Recently, many over 100W output power GaN HEMT amplifiers have been developed. Especially, much attention is paid for Class-E GaN HEMT amplifiers, which will be used in mobile communication infrastructure systems. In general, class-E operation mode is used for such amplifiers for its simplicity. However there is a principle limitation of operation frequency or output power for class-E operation. In this paper a new class of amplifier is developed to overcome the limitation. By realizing intermediate operation mode between class-E and class-F, 360W output power and 65% power added efficiency was successfully obtained.
