Abstract(in English) | High efficiency power amplifiers operating at multiple frequency bands are required for advanced mobile communication systems, which have multi-band capability. For a high-efficiency approach, we have proposed a harmonic reactive termination technique, in which harmonics are treated with the optimum pure reactance for a transistor. In this work, a dual-band GaN HEMT power amplifier with second harmonic reactive source and load impedances has been developed at 2.1-GHz and 2.6-GHz bands. The fabricated amplifier has achieved a high-efficiency operation with maximum power-added efficiencies of 72% and 61% and associated output powers of 36.7 dBm and 37.1 dBm at 2.13 and 2.6 GHz, respectively. |
