• 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


    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…

  • HMC799: PD capacitance


    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?



  • 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…
