摘要
介绍了锁相环路频率合成器的应用、由单片机控制的大规模集成锁相环频率合成器总体方案,主要电路的设计与偏程,调测结果及其改进,该合成器的工作频率范围为900 ̄1000MHz,频率间隔为1MHz,单边相位噪声功率谱密度为-76dBc/1Hz/1kHz。
This paper introduces the application of PLL frequency synthesizer, its total plan of single-chip microcomputer control,design of the main circuits, programming, adjuste-ment, measurement results and improvement. The synthesizer's frequency ranges 900 ~1000MHz,frequency separation being 1MHz and signle-sideband phase noise spectrum densi-ty -76dBc/lHz/1kHz.
