A 2.1/2.6 GHz dual-band high-efficiency GaN HEMT amplifier with harmonic reactive terminations

A dual-band high-efficiency GaN HEMT amplifier with harmonic reactive source and load impedances has been developed at the 2.1-GHz and 2.6-GHz bands. Many circuit components are required for this type of amplifier, since many frequencies have to be treated, which induces circuit loss. Here, a design strategy to avoid an efficiency reduction due to circuit loss is introduced. The fabricated dual-band GaN HEMT amplifier has achieved maximum power-added efficiencies (PAEs) of 72% and 61% with 36.7- and 37.1-dBm output powers at 2.13 and 2.6 GHz, respectively.
