Outline of Final Research Achievements |
Toward the 5th generation wireless communication system, the demand for microwave power amplifiers with even higher performance, such as power efficiency, is increasing. In this project, a new harmonic tuning circuit for class-F power amplifier based on composite right-/left- handed transmission line stub was successfully proposed. The performance and applicability of the novel harmonic tuning circuit was demonstrated by applying them to various kind of prototype circuit. For example, by applying the harmonic tuning circuit to a class-F power amplifier using 2 GHz/4 GHz-band 5W GaN FET, a drain efficiency as high as 88% was demonstrated even though the harmonic tuning circuit was considerably miniaturized compared to conventional ones. The developed method has wide range of applications for sophisticated microwave circuits required in next generation system.
