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.
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.
