• HMC661 S-parameters

    Hi,

    Are single-ended and differential one-port S-parameters for the two sampling inputs on the HMC661 available?  I can't find them on the datasheet or web page.

    Thanks!

  • HMC661- Offset in output pins for DC coupling

    My application consists of connecting HMC661 with Xilinx RF SOC ADC (ZCU111 board) with sampling at 2GSPS. The ADC has Vcm of 1.25V. But I want ADC and HMC661 connected DC  coupled. 

    HMC661 datasheet says that Vob pin can have voltage between 1 to 3 V and…

  • RE: HMC760 / HMC661 Minimum Clock Frequency Limitation?

    Hi Engineer Zone experts,

      I am looking for the answer to the same question as previously posted Jan 5, 2018.

    The answer on Jan 18, 2018 was telling us the performance alters significantly due to droop.

    Continuing the thoughts, what if the droop happens…

  • RE: interfacing HMC661 with Xilinx Rf SOC ADC

    Hi,

    I'm not sure about the XiLinx input, but the HMC661 output is 50 ohms per port, or 100 ohms differential.  If you don't need DC operation, you can just connect the amp and ADC with series caps.  

    Thanks,
