Abstract
Many systems require that the frequency synthesizer provide high performance in frequency agility and low phase noise characteristics.A design and implementation of frequency hopping synthesizer based on ADF4350 and AD9913 is presented.Based on studying the theory of frequency hopping and phase locked loop,and analyzing the internal structure of ADF4350,a design of frequency hopping synthesizer ranging from 900 MHz to 4 000 MHz is realized combing with AD9913.Testing results show that the phase noise is lower than -86 dBc/Hz@10 kHz,frequency hopping step is 0.76 Hz,and frequency conversion time is 175 μs,which provides a good performance and meets the requirement.关键词
