【摘要】：随着测试仪器的发展,高频段信号的应用越来越多,因此对高频信号测试系统的性能要求也不断提高.本文在基于高性能的低频窄带合成源的基础上,提出一种通用的超高性能高频宽带合成源设计方案.本方案采用分频锁相和混频锁相组成的双环锁相模式,在分频锁相模式下,信号进行快速锁定,实现宽频段内信号的大幅度切换;在混频锁相模式下,通过引入不同频段的窄带信号与VCO的反馈信号进行混频鉴相获得超高性能的宽带信号,最终实现宽带高频信号的稳定输出.
[Abstract]:With the development of testing instruments, the application of high frequency signal is more and more, so the performance requirement of high frequency signal testing system is improved. On the basis of high performance low frequency narrow band synthesizer, this paper presents a general design scheme of high performance high frequency and wide band synthesizer. In this scheme, a dual-loop phase-locked mode is used, which is composed of frequency division phase lock and mixed frequency lock. In the mode of frequency division phase lock, the signal can be locked quickly and the signal can be switched greatly in the wide band. In the mixed-frequency phase-locked mode, the ultra-high performance wideband signal is obtained by introducing the narrowband signal of different frequency bands and the feedback signal of VCO to obtain the ultra-high performance wideband signal, and the stable output of the wideband high frequency signal is realized.
