摘要:

利用锁相环(PLL)和YTO相结合,设计出一种频率合成器。实现了3~7 GHz的频率覆盖和低于0.2 Hz的频率分辨率。全频段相噪均在-108 dBc/Hz@10 kHz以下,具有较高的实用价值。

关键词: 频率合成器, 锁相环, DDS, YTO

Abstract:

A frequency synthesizer is designed by using PLL and YTO in this paper.A 3~7 GHz wide frequency coverage is implemented with a frequency resolution less than 0.2 Hz.The phase noise level is less than -108 dBc/Hz@10 kHz in all bands.It has a high practical value.

Key words: frequency synthesizer;PLL;DDS;YTO
