| Abstract: | This paper introduced the internal structure of ADF4350 PLL frequency synthesizer. In this foundation, the paper analysis the basic principle and operating characteristic of the ADF4350 PLL frequency synthesizer. Combined with characteristic of the ADF4350 PLL frequency synthesizer, the paper gives a design method of frequency source of ADF4350 PLL frequency synthesizer controlled by AVR Single-Chip Processor. The paper utilizes simulation software ADIsimPLL to simulate and design loop filter. Through debugging the hardware circuit of the Phase Locked Loop and writing the Single-Chip Processor program, a good performance frequency source is realized. |
