摘　　要：软件无线电技术在无线通信系统的发展中具有重要的历史地位,其使得无线电通信系统具有很好的通用性和灵活性。通过与传统模拟调制器实现方案对比,指出了基于软件无线电思想的数字化中频调制的优势所在。在介绍硬件平台组成的基础上,详细给出了EV12DS130A和HMC830LP6GE电路设计方法及注意事项。以FPGA作为数字信号处理平台,研究了软件设计原理与实现方法。最后进行了系统测试,并给出了实测结果。Software defined radio （SDR） is praised as a revolution in the development of wireless communication which makes wireless communication system common and flexible. Based on a comparison with the traditional analog modulator, the advantage of digital IF modulator based on a unified hardware architecture is indicated. The circuit design method of EV12DS130A and HMC830LP6GE is described based on an introduction of the hardware platform.Using FPGA as the digital signal processor,the software design principle and implementation method are studied.At last,some results of the system testing are given.
