【摘要】 阐述了宽带微波取样混频器的工作原理,分析了其与一般平衡式混频器的区别。同时对脉冲信号发生器也做了研究。通过对取样器的分析设计,得到了实际的测试数据,表明此混频器能在0.03GHz~3GHz的射频范围内与较低的本振混频得到几百kHz的中频,宽带混频效果明显。更多还原

【Abstract】 This paper expands the working principle of microwave broadband sampling-mixer,analyses the differences between the balanced-mixer.It designs the pulse generator and the sampler and gets the actual test data,it shows that the mixer can work effective at the frequency of 0.03GHz～3GHz.更多还原
