| Abstract: | Digital PLL frequency synthesizer has the simple structure, low cost, and preferable phase noise characteristics, which make it being widely, used in communication satellite earth station systems. The application of digital PLL frequency synthesizer in communication satellite earth station was discussed. Furthermore this paper also gaves an engineering example using a high integration PLL: PE3336 to design a PLL frequency synthesizer with Ultra - low phase noise, and it had been used in a sort of communication satellite transponder earth station system. |
