This paper introduces the loop filter of phase locked loop frequency synthesizer composed of PE3236 or ADF4107. According to transfer functions of the loop filter and the single phase locked loop system, it figures out the loop filter's parameters, and introduces the selection of loop bandwidth.Then it presents examples to introduce the option and calculation of the loop beadwidth, and deduces the stability of the system according to Bode Rule.
