| Abstract: | A frequency synthesizer based on ADF4153 is designed and implemented.The architecture and circuit schematic diagram of the frequency synthesizer are given in this paper.The performances of phase noise and spur are analyzed and some measures are proposed to improve the phase noise and spur.The stability of the loop is analyzed too.The test results show that the phase noise of the frequency synthesizer can reach-96.59dBc@10kHz,the spur suppression is greater than 45dBc,and the frequency synthesizer works stab... |
