随着高频技术的发展,微波能量传输系统中常采用更高的频率,为了整流天线能得到高输出电压,并且减小系统体积,降低装置成本,设计了一种C波段微波微波锁相环频率合成器。通过以ADF4106作为核心电路,选用合适的压控振荡器芯片,确定鉴相频率、分频系数,并且详细分析了环路滤波器结构及其参数,并利用仿真软件对锁相环仿真,得到的仿真参数与计算结果基本一致。该系统具有极高的工作频率,省略了许多高频系统中的倍频部分,简化了系统的结构,降低了装置的成本。

With the development of high frequency technology, microwave energy transmission systems are often used in higher frequency.In order to rectifying antenna can get high output voltage,reducing the system volume and reducing the cost of the device,a C-band microwave phase-locked loop frequency synthesizer is designed.Through to ADF4106 as a core circuit,choose suitable pressure controlled oscillator chip,determine Phase discrimination frequency,frequency division coefficient,loop filter structure and parameters,and the phase lock loop（PLL）is simulated,the related loop parameters and algorithms for computing results are basically the same.The system has a very high operating frequency, omitted many of the frequency doubling of the high frequency system,simplifying the structure of the system and reducing the cost of the device.
