摘　　要：为了降低数字预失真硬件平台的成本,本文提出了运用Xilinx公司的ZYNQ 7000系列SoC,并使用8层PCB层叠设计的技术方案,以便大幅度降低硬件成本。文中首先完成了硬件电路原理图设计,然后进行高速电路PCB设计并生成Gerber文件,之后进行PCB板的外加工打样,最后调试装配好的硬件电路,并对其进行预失真线性化实验验证。实验结果表明,利用性价比较高的ZYNQ 7000系列SoC完全可以实现功放数字预失真线性化电路,达到预期的技术指标。In order to reduce the cost of digital predistortion hardware platform,this paper puts forward to use ZYNQ 7000 series SoC and 8 stack-up PCB to largely reduce hardware cost.First of all,this paper complete the schematic design for the hardware circuit,then conduct high speed circuit design and generate Gerber files.After that,the PCB will be manufactured by the external service provider.Finally,the hardware circuit is debugged and the predistortion linearization experiment is applied to it to validate its performance.The experimental results show that using the cost-effective ZYNQ 7000 series SoC can fully realize the digital predistortion circuit for power amplifiers.
