摘要
本文实现了一种高效率频率可重构AB类功放,通过阻抗拟合算法优化匹配结构,实现了不同频率条件下的复阻抗与50Ω输出负载阻抗的同步匹配,提升漏极效率(DE)并拓展了带宽。测试结果表明,在2.2~2.6 GHz的400 MHz内,饱和输出功率为39.74~42.05 dBm,漏极效率为62.29%~76.19%;在3.1~3.5 GHz的400 MHz内,饱和输出功率为41.03~42.71 dBm,漏极效率为46.91%~71.19%。
A highly efficient frequency-reconfigurable Class AB power amplifier is presented.By optimizing the matching structure through impedance fitting algorithms,it achieves synchronous matching of complex impedance with a 50Ωoutput load impedance under different frequency conditions,thereby improving Drain Efficiency(DE)and extending the bandwidth.Test results show that within the 400 MHz band from 2.2 to 2.6 GHz,the saturated output power ranges from 39.74 to 42.05 dBm,and the DE ranges from 62.29%to 76.19%;within the 400 MHz band from 3.1 to 3.5 GHz,the saturated output power ranges from 41.03 to 42.71 dBm,and the DE ranges from 46.91%to 71.19%.
