摘　　要：频率源是微波收发系统中的重要组成部分，能够为收发系统提供本振激励信号。本文介绍了一种用于c波段收发系统中的锁相环频率源，重点分析了频率源的关键器件的选型、寄存器的设置方法以及用于抑制谐波、杂散的薄膜带通滤波器的设计。将本文设计的频率源和收发通道进行联调，测试结果表明该频率源能够满足收发系统的要求。The frequency source is an important component in the microwave transceiver modules which implements local oscillators in the up -conversion and down -conversion sections of wireless receivers and transmitters. In this paper, it introduces a C -band phase lock loop（PLL） frequency synthesizer and focuses on the selection of critical component ,the writing of ADF4156 registers and the design of film microwave band - pass filter which could reduce the spurious of signal. The result which is tested by uniting frequency synthesizer and transceiver shows that the designed PLL frequency synthesizer conforms to the requirements of the transceiver modules.
