摘　　要：介绍点频、三位小数分频销相频率合成器的研制，以及采用附加滤波器抑制小数杂散干扰的方法。A frequency synthesizer with fractional-N phase-locked loop is introduced. Its output is the dot-frequency signal and there are three decimal places for the tribution ratio. The technique for adopting additional filter to restrain the spurious noise is also described in this paper.
