Based on Phase-Locked Loop the ADF4350 Filter Design

Abstract:

Based on the basic principle of the phase locked loop, analyzes the structural characteristics of the loop filter technology and ADF4350; secondly, design and analysis of two order passive low pass filter, three order passive low pass filter, two order active low-pass filter, with parameters such as bandwidth, phase margin ADF4350 PLL, selection the loop filter is suitable for the actual situation; using ADIsimPLL software to determine the parameters and realize the optimization of S parameters on circuit simulation, optimized and then use ADS software to observe. Finally, according to the results of analysis to adapt to the situation three kinds of filter structure of ADF4350phase locked loop.
