Linearization of Analog Domain Power Amplifier Based on Two-channel Nonlinear Feedback Architecture

  • 摘要: 该文提出一种在模拟域抑制功率放大器(PA)非线性失真的双通道非线性反馈架构,以改善PA线性度,减少邻道泄露。在该架构中,用于抑制非线性的电路包含非线性提取环路和反馈调整环路。非线性提取环路通过耦合器提取PA输入和输出信号,进行幅度和相位对齐后抵消线性信号,保留PA产生的非线性失真。反馈调整环路包含两条独立反馈通道,且信号通过非线性提取环路和反馈调整环路中两条通道分别反馈后的总时延具有两倍关系,使反馈环路呈现2阶Delta-Sigma结构形式,相比于单通道非线性反馈架构具有更好的失真抑制性能。并且通过所提方法配置反馈通道参数,可以实现不同目标频点下非线性失真的灵活抑制。最后设计了一个使用CMPA0060002F商用功放芯片的实验平台,对于带宽为40 MHz,载频为780 MHz的测试信号,在当前6 ns的硬件反馈时延条件下,可以使邻道功率泄露比(ACLR)单边带改善11 dB或双边带改善6 dB,且通过减小反馈时延能够取得更好的性能。
