X波段跳频微波接收机的设计

文章介绍了一个X波段具有本振跳频功能的微波接收机的设计、研制和调试。文章首先对接收链路的指标进行了分析和计算，其次结合直接数字频率合成（DDs）和锁相环（PLL）技术完成了X波段跳频本振源的设计，重点分析了跳频本振源的低相噪、低杂散设计方法，通过软件仿真给出了环路跳频时间。最后对样机的测试结果表明，该方案接收机主要技术指标满足工程要求。

Design of an X - band Receiver with Frequency Hopping

This paper describes an X--band receiver with frequency hopping. First, it analyses and calculates pivotal targets of receiver link. Then, an X--band local oscillator is completed based on DDS and PLL. Deeply, it describes implementation of low phase noise and low spurious, the time of frequency hop is given using software simulating also. At last, the test results indicate that the receiver can meet the needs of project practically.
