Design of a New Multi-Function Centimeter Wave Frequency Synthesizer
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.
