In this paper, a novel real-time active matching circuit design process based on preliminary measurements and a hybridization of a genetic algorithm and a data mining method is discussed. As a result, our proposed matching circuit can potentially have higher dc output power at 92.0 % and 69.6 %of potential load combinations with a maximum matching performance improvement of 21.4 % and 37.6 % compared...
This paper presents the design of a dual-band power amplifier operating at 2.4 GHz and 3.35 GHz. The proposed topology is based on the use of composite right/left-handed unit cells. A composite right/left-handed cell exhibits a dualband frequency response at an arbitrary pair of frequencies because of its phase characteristics. A power amplifier based on an enhancement mode pseudomorphic HEMT transistor...
