| 摘要: |
| 本文提出一种新的快速跳频频率合成器方案。它通过采用脉冲内插变频鉴相和取样—保持—直接电压预置两种方法,使得电路具有换频速度快、输出信号频谱纯、以及易达到高的频率分辨率等优点,且实现容易。文中给出了实现框图和部分关键电路,并对其工作原理作了详细的说明。最后,对环路性能进行了分析。 |

| Abstract: |
| This paper introduces a new type of fast hopping frequency synlhesizer,Which accelerates the loop's frequency switching time and improves frequency spectrumby pulse installing varying-frequency phase-detection and by sample-hold-direct voltageset. This synthesizer is easy to realize by circuit. This paper gives detail diagram
and some key circuit and discusses its principle. At last, loop's per-formance is analyzed. |
