upconverter meaning in Chinese

上变频器增频变频器
升变换器
升频器上转换器
向上变频器

To meet the waveform requirements , dds + multiplier + upconverter was used to realize the c - band fmcw frequency source
为满足波形参数要求,本文设计了dds +倍频+上变频的c波段三角形调频连续波频率源。
Secondly , we used the dsp assembly language to perform the carrier phase tracking based on a digital processing system . this system is designed according to the idea of software radio . this digital processing system realized the intermediate frequency digitalization . with the diverse configuration of the digital upconverter and digital downconverter in this system , it can carry through many signal modulation modes . and because the carrier phase trac king is performed using software in dsp , it brings great convenience to this system and makes this system available in many digital communication systems
在该数字处理平台上可通过加载不同的软件对平台中的数字上下变频器进行灵活的配置以实现不同的数字调制解调制度，通过将载波的相位跟踪工作放在dsp软件中进行带来了很大的灵活性，能够适用于当前许多种数字通信系统。
