摘要:

随着移动通信测试仪器的发展,宽带高性能频率合成器成为其设计的难点,文中利用双锁相环(PLL)结构和Σ-△小数分频技术,设计出一种高性能频率合成器。实现了2 000~4 000 MHz的频率覆盖和低于003 Hz的频率分辨率,全频段相噪均在-105 dBc/Hz@10 kHz以下。测试结果满足宽带高性能频率合成器的设计要求,具有较高的实用价值。

Abstract:

With the rapid development of mobile communication test equipment, it is the difficulty of the design that is wideband high performance frequency synthesizer. A high performance frequency synthesizer is designed by using double PLLs and fractionalN based on SigmaDelta technology in this paper.  A 2 000~4 000 MHz frequency coverage is implemented. A frequency resolution is less than 0.03 Hz. The phase noise level is less than 105 dBc/Hz@10 kHz in band. The test result meets the design requirements of wideband high performance frequency ynthesizer It has a high practical value.

Key words: frequency synthesize, PLL, VCO, frequency mixing
