| Abstract: |
| An L-band frequency synthesizer is designed,the main configuration of which is the chip PE3236.The voltage preset circuit is introduced to control the voltage of VCO,in this way,the time of frequencyagility can be reduced,and the requirement of low spurious,low phase noise,and fast frequency-agility is achieved.In addition,the reliability of the circuit is high,so it has practicability. |
| Key words: frequency synthesizer,PLL,VCO,low pass filter,frequency-agility,frequency preset |
