When it is realized by using the analog devices, the conventional quadrature coherent detector may result in the large image frequency errors.
传统的正交相干检波器由模拟器件构成，存在较大的镜频误差。
The main structure of the mixer adopts two symmetrical single-balanced mixers, with phase-shifting of the up and down path signals to eliminate the image frequency.
混频器主结构采用两只对称的单平衡混频器组合，通过上下两路信号移相来达到消除镜频的目的。
Then we perform digital pre-compensation method, which can be used in the processing of base band signal to reject image frequency and protect carrier leak to meet the application purpose.
然后采用对基带信号的数字预补偿方法来抑制镜像频率和载波泄漏，从而达到应用的目的。
