| Abstract: | The design of broadband PLL frequency synthesizer used in terminal guidance radar is introduced. First, the design selections and the system phase noise parameter are analyzed. Then the characteristics of PLL synthesizer chip and the design method of loop filter are described, and the parameter calculation and simulation analysis is given. Finally, the test result meets the system parameter. Such frequency synthesizer has the advantages of wide output bandwidth, low phase noise and low spurious. |
