摘 要: 介绍一种基于GPS驯服钟的新型高频信号源。以GPS驯服钟输出的高稳定频率信号作为基准,并通过5×5的谐波倍频和2×2的乘法倍频将10 MHz的基准时钟信号倍频至1 GHz作为AD9910参考时钟,再通过MCU对AD9910的频率控制,实现了50~200 MHz的高稳可控高频信号源系统,测试结果理想。
关 键 词: 信号与信息处理;50~200 MHz高频信号源;GPS驯服钟;AD9910;倍频链电路

Abstract: This paper introduces a new high frequency signal source based on GPS taming clock. Adopting the high-stability frequency signal of GPS taming clock as the reference benchmark, the standard 10 MHz signal is multiplied to 1 GHz with 5×5 harmonic frequency multiplication and 2×2 multiplier frequency multiplication. The 1 GHz signal is sent to AD9910 as the reference clock. And the frequency control of MCU to AD9910 is adopted. As a result, a highly stable and controllable high-frequency signal source system of 50-200 MHz is realized. The test results are satisfactory.
Key words: signal and information processing; 50-200 MHz high-frequency signal source; GPS taming clock; AD9910; frequency multiplier circuit
