摘要:
利用一种渐变尺寸的光子带隙结构的带阻特性,来抑制功率放大器输出端的二次谐波分量,通过减小消耗在二次谐波分量上的能量来提高功率放大器的输出性能.为了尽量减小PBG结构对功率放大器基频分量的影响,对所选择的PBG结构的尺寸参数进行了优化.通过实验分析证明了优化后的PBG结构可以在很宽的频段内(6.9~7.5 GHz)有效地改善功率放大器的输出特性.
Abstract:
A tapered photonic bandgap structure is proposed to suppress the second harmonic of a power amplifier and improve its output characteristics by decreasing the energy wasted in the second harmonic. In order to minimize the influence of the proposed PBG structure on the fundamental frequency at the output of the power amplifier, the novel PBG structure is optimized and a PBG structure based on the optimized parameters is designed.The experimental results verify that the optimized PBG structure can effectively improve the output performance of the power amplifier in a wide frequency range of 6.9-7.5 GHz.
