The thesis describes a prototype fractional frequency synthesizer which is supported by a project granted by the ministry of science and technology of pr china. firstly, based on the principle of pll, this paper briefly describes three basic pll components : phase detector ( pd ), low pass filter ( lpf ), voltage controlled oscillators ( vco ), analyzes the linearized pll and summaries the transfer functions of third - order pll with ideal intergrator filter respectively. based on a microwave vco, the single point frequency pll frequency ranging from 2. 2 to 2. 5ghz is developed
首先，從鎖相環的基本理論、原理出發，分析了鎖相環中的三個基本部件：鑒相器、環路濾波器和壓控振蕩器，此後，針對線性化鎖相環進行了分析，研究了在使用比例積分濾波器時，三階鎖相環的環路參數計算；在電路實現時選用了lmx2353 ，在此基礎上，完成了2 . 2 ~ 2 . 5ghz范圍內的小數頻率合成器設計。
