宽带低相噪高分辨率频率合成器设计

摘要

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.%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。
