| Abstract: | The frequency synthesizer has important influence on the performance of modern radar.The design of a S-band digital phase-locked loop frequency synthesizer is described in detail in this paper.The master-slave double phase-locked loop design is applied in the frequency synthesizer.The frequency-division coefficient of the loop is reduced and the problems such as phase noise,spectrum purity,frequency hopping in large range,and miniaturization are well resolved.The frequency synthesizer is characterized by lo... |
