摘要
该文介绍了一种新型多功能厘米波频率合成器,利用锁相倍频的方式,首次将直接数字频率合成器(DDS)输出的连续波(步进 1 MHz)、常规脉冲、重频抖动、重频参差、双脉冲、捷变频信号、组变信号、二相编码和线性调频等信号搬移至 0.8～18 GHz频段,外形尺寸为 76 mm×70 mm×10 mm,体积约为传统类似频率综合器项目的 1/20,具有工作频带宽、频率高、体积小等优点.
Abstract
This paper proposes a novel multifunctional centimeter-wave frequency synthesizer.The proposed synthesizer,for the first time,moves the continuous wave(step:1 MHz),conventional pulse,double frequency jit-ter,double frequency stagger,double pulse,agile frequency conversion signal,group variable signal,two-phase coding,and linear frequency modulation signals from direct digital synthesis(DDS)to 0.8-18 GHz frequency band via phase-locked frequency doubling.The overall size of the device is 76 mm×70 mm×10 mm,and its volume is approximately one-twentieth that of the traditional frequency synthesizer.Thus,it affords the advantages of a wide working band,high frequency,and small size.
