摘要
介绍一个高性能差拍器的设计思想及具体实施考虑。该差拍器的相位噪声小于0.1ps,特别适用于双混频时差测量系统和利用差拍周期法的频率测量系统。
Design ideas and technical considerations of a gigh performance beater are described in this paper. The input frequency range is from 1MHz to 100MHz. The phase noise is smaller than 0.1ps. This beater can be used for the dual mixer time difference (DMTD) system and for the frequency measurement system using beat period method.
