• HMC799 Overload Recovery

    I am using the HMC799 with APD input. As the APD can generate high currents I have used a Schottky diode connected to the input to divert some of this current. The internal bias on the CFILT pin is 2.2V when Vcc is 5V. I notice on a previous post on this…

  • HMC799 EVB - Transimpedance amplifier

    Hi,

    Is it possible for you to provide Altium files of the layout of HMC799LP3E EVM board. I need a full PCB layer stack-up definition and diagram with dielectric material. I also need the trace width and all information on your Evaluation printed circuit…

    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 SPICE can't be found in the model library of company's website. Can you provide one?Thanks

    hi,

    HMC799 SPICE can't be found in the model library of company's website.

    Can you provide one?

    Thanks.

  • HMC799: PD capacitance

    Hello,

    do you have information which maximum PD capacitance can be handled by the HMC799?

    Since I cannot see any option for external compensation.

    A second question: Do you think FR4 would work?

    Thanks,

    Manuel

  • RE: HMC799 Photodiode Pre-amp

    Hi Sinan,

    I am currently using the HMC799 with a PIN PD. But, since I also need the DC output, I am operating it without the 22nF capacitors at PIN 3 and PIN 10. Moreover, the current from the PD is in the microamps range (so does not saturate the TIA…

    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
