摘　　要：详细讨论了含混频器的频率合成器中混频器杂散对频率合成器输出频谱的影响,并导出了频率合成器输出频谱中由混频器杂散引起的杂散分量SI(Ωi)的计算公式,从而为含混频器的频率合成器抑制混频器引起的频谱杂散分量提供了理论依据和技术途径。The influence of mixer spurious on output frequency spectrum of a frequency synthesizer including mixer is analyzed in detail , and the calculation formula of spurious component S1 （Ω1） in output frequency spectrum of frequency synthesizer due to mixer spurious is derived. Therefore the theoretical basis and technological approaches are presented for reducing the spurious of frequency spectrum resulting from mixer spurious in the frequency synthesizer including mixer.
