镜像抑制混频器 meaning in Chinese
image reject mixer
image-reject mixer
Examples
- X - band image - reject mixer design
波段镜像抑制混频器设计 - The commonly used passive mixer is also discussed and a single balanced mixer is designed . then the theory of image rejection mixer and factors that affect its performance are presented
对混频器的讨论，先是设计出了一个性能理想的单平衡混频器，随后阐述了镜像抑制混频器的原理和影响其性能的因素。 - For the application of direct broadcast satellite ( dbs ) , a ku - band high image rejection broadband mixer is designed using ads . it appears predominant performances when compared with common single balanced mixer
针对卫星电视直播接收系统，用ads设计了一个宽频带、高镜像抑制度、低噪声的ku波段镜像抑制混频器，并同普通平衡混频器进行了对比分析，显示了其优越的性能。 - In former , image - reject mixer uses phasing to differentiate between two single - balance mixers . it ' s four diode is type of dmk - 2606 by made alphar corporation , module of mixer ' s integrated circuit is simulate by senerade 8 . 0 and ads software
然后介绍了混频器的基本原理，设计了镜像抑制混频器和上变频器放大电路，镜像抑制混频器是利用两个单平衡混频器的相位差对镜频进行抑制，其中四个混频二极管采用alphar公司dmk - 2606型。 - This ku - band three channel receiver consists of spst modules , lna modules and image rejection mixer modules . these modules were designed and tested separately , then were assembled to the whole receiver . all the circuits were designed with small - sized devices so as to reduce the total size of the receiver . and the noise figure was considerably reduced because of the image rejection mixer
另外，由于采用了镜像抑制混频器，从而使整机噪声系数大为降低。在设计方法上，本文采用了先进的微波电路设计软件ansoftserenade对所有的电路和系统进行设计、优化和仿真，大大的缩短设计周期，提高设计效率。
