| 摘 要： | 推导出了吞脉冲技术锁相环频率合成器的输出频率Ｆｏ、双模前置分频器的输出频率Ｆｐ和参考频率Ｆｒ之间的关系式．经宽覆盖（１３８．０００～１６７．０００ＭＨｚ）、高稳定度（１０－６）、多通道（每通道间隔２５ｋＨｚ）频合器实验论证,关系式成立．应用此关系式提出了一种新的小数分频理论和实现电路框图,该理论能解决单环频合器中高鉴相频率与高频分辨率之间的矛盾．

| Abstract: | According to the theory of swallowing pulse PLL frequency synthesizer, the formula of the broken number frequency dividing ratio or the relation between Falt and F o of frequency divider, i.e. Falt= F o/( P+A/M ), are derived. A new broken mumber frequency division theory and a circuit diagram to realize the theory are proposed. It has settled the contradiction between the high pulse detection frequency and the high frequency resolution of the single PLL frequency synthesizer. |
