摘要

为了降低基于锁相环的微波频带频率合成器的相位噪声，提出了将压控振荡器的输出信号与Lo信号混合并检测中频信号的方法。然后，设计了兼容环路滤波器。最后，实验结果证明，改进频率合成器的相位噪声大大低于直接锁相合成器。

A C-band Low-noise Frequency Synthesizer Based on Digital Phase-locked Loop

To reduce phase noise of microwave-band frequency synthesizer based on phase-locked loop(PLL), the method that the output signal of VCO is mixed with a Lo signal and the IF signal is detected, is proposed. Then, the compatible loop filter is designed. Finally, the experimental results prove that the phase noise of improved frequency synthesizer is greatly lower than that of directly phase-locked synthesizer.
