• HMC799

    请问HMC799跨阻放大器能否连接光电二极管?
    输入的2.1V偏置是芯片内部给的,还是外部加上的?
  • HMC799

    买的HMC799芯片发现芯片12引脚和10引脚是直接导通的,按照datasheet的要求就是把3引脚和10引脚的22nf电容去掉,测试发现没输入任何信号输出端口有一个4V左右的直流偏置,这是为什么?难道是买的HMC799芯片有问题?发现买的hmc799芯片12引脚和10引脚都是直接导通的,不知道是不是本来就是导通的?求工程师解答一下,谢谢!

    HMC799芯片跨阻放大器可以设计成直流耦合吗?就是把两个C7电容去掉行不?会不会影响性能

  • HMC799 feedback capacitance

    Hi,

    I'm working on a photodiode circuit design using HMC799. When I calculate and evaluate the noise gain, I couldn't find any information related to the parasitic capacitance of the feedback resistor. As the feedback resistor is integrated inside the…

  • Pin11 of HMC799

    hi,

    looking at the datasheet of HMC799, the Pin11 is N/C on Functional Diagram and Schematic, but on PCB layout, pin11 is connected a capactor C11 to GND.  

    i designed a PCB without C11, the output returnloss is very poor.  is it C11 necessary?

    thanks…

  • HMC799 TIA oscillation

    Hi,

    I'm trying to build a trans impedance amplifier for the photo-diode (homodyne detector) for frequencies above 200 MHz. I used a diagram from the HMC799 Data sheet. But amplifier generates a sine signal frequency of about 640 MHz. Could you tell me…

  • HMC799 Overdrive Recovery Time

    When evaluating the HMC799 TIA on a custom PCB (not AD Eval PCB) I have been observing
    overdrive recovery times of ~30ns at the output when the input is overdriven by
    a 20mA pulse. Is this what would be expected? The trace on page 11 of the data
    sheet…

  • Question on HMC799

    Planning to use HMC799: can I apply +3V to VCC2, when VCC1 and VCC3 is under +5V?
