...起线性I/Q 调制(linear I/Q modulation)的设计, 极化调制可以降低输出频谱的噪声电平(noise level)及杂散电平（spurious level）。②可降低工作电流, 主要是由于功率放大器工作在高效率的饱和区。

A method to realize a wide frequency-coverage frequency synthesizer with low spurious level and low phase noise level is proposed in this paper.
提出了一种实现宽覆盖、低相位噪声、低杂散的频率合成方法。
With the development of modern electronic technology, frequency synthesizers are required to have wider band, higher resolution, short frequency switching time and lower spurious level.
随着现在电子技术的进步，系统对频率合成器的精度、频率分辨率、转换时间和频谱纯度等指标提出了越来越高的要求。
