摘　　要：针对软件无线电应用,对多相滤波器与多相数控振荡器(NCO)结构进行了分析和扩展,提出一套可实现任意整数倍上变频的频点可灵活配置的数字射频发射机方案.测试结果表明,本设计能够按照设计要求将低速数据实现任意倍数上采样并可调制到任意载频,在数字域完成基带到射频的转换输出,满足设计要求.A method for arbitrary integer multiple up-converter of the frequency and flexibly configured digital RF transmitter with poly-phase filter and multiphase numerically controlled oscillator（NCO） on SDR is proposed. The test results show that this design can be in accordance with the design requirements of the low speed data sampling and can realize arbitrary multiple modulation to any carrier frequency, complete the conversion from baseband to RF output in the digital domain, meets the design requirements.
