• HMC683混频器转换增益为负的原因?

    首先对于下变频器的转换增益存在这样的问题:

    下变频器的转换增益的基本定义也是:Prf/Pif 吗?(即射频信号的功率比上中频信号的功率)?

    还是说对于下变频器而言,转换增益重新被定义为:Pif/Prf ?(即中频信号功率比上射频信号功率)?

    本人按照HMC683混频器芯片的datasheet的评估板电路原理图设计了相应的PCB版图,并使用精度尽可能高的电子元器件,同时按照datasheet上提供的测试条件,将Bias电压设置为2.5V,Vcc电压设置为5V(相应偏置电压及电源电压在板子上电情况下已测试满足实际要求…

  • RE: 36GHz RF oscillation signal source

    You need a PLL which drives a frequency doubler which drives an amplifier. Possible choices might be ADF4371 (PLL),  HMC1105 (frequency doubler) and HMC7229 (amplifier). These are not the only choices.
