| Abstract: | The DDS chip AD9910 is adopt,in which internal clock is 1 GHz and the maximum output frequency is 400 MHz,and the fast hopping frequency synthesizer is designed which broadband is 500 MHz.The AD9910's spurious free dynamic range(SFDR)is analysed and the appropriate frequency band is selected to finish fast broadband frequency hopping.In the premise of ensuring low noise,fast hopping frequency synthesizer of which bandwidth is 500 MHz and the frequency hopping time is less than 1 us is designed in mixing met... |
