| Abstract: | in many fields, the direct frequency multiples is a leading way in frequency synthesizing. By multiplying the frequency of crystal Oscillator in means of single Step Recovery Diode we can gain Microwave.This paper introduces a method for designing a comb source which has a wide frequency ranges .the advantages of this new method includes SSB phase noise , high frequency resolution, simple circuit, and so on..After validated by making an experiment circuit board, both the frequency ranges ,SSB phase noise and frequency resolution of the experiment board reach the demand of advance design, so that the experiment achieves expected effect. |
