A Dual-band High-efficiency Power Amplifier with Small Frequency Ratio
A dual-band high-efficiency power amplifier with small frequency ratio is implemented by effectively incorporating the Class-F and inverse Class-F modes. The multiple harmonic control and the dual-band matching techniques are employed to design the matching networks. For demonstration, a dual-band power amplifier operating at 1.8 GHz and 2.4 GHz was designed, fabricated and measured. The measured results show that the implemented power amplifier achieves a high PAE of 66.49% and 63.74% at 1.8 GHz and 2.4 GHz respectively. The performance measured at two operating frequencies are similar in gain, bandwidth, efficiency and maximum output power.
