• RE: HMC659 biasing sequence

    Hi Kagan,

    Thanks for your answer.
    Is the inquired biasing sequence applicable to all non-self-biased HMC amplifiers that have Vgg1 and Vgg2? Or is it applicable to specific non-self-biased HMC amplifiers? I would like to known it for supporting other…

  • hmc-980


    I would like to use the HMC-980 as an active bias controller for the HMC-1049. I see that there are generic circuits in the HMC-980 data sheet, but do you have a specific one for use with the HMC-1049? Also could you tell me if these two devices…

  • RE: Need to cool for amplifier module package ?

    Both the HMC-C004 and the HMC-C016 need to be mounted to be cooled.  As stated in the outline drawing "Bottom to be held at 85 degrees C max.".

  • RE: HMC-MDB277

    Hello Mark

    I really appreciate for your helpful reply.

    I could understand that HMC8118 and HMC7586 can be utilized to up-convert and down-convert the input data.

    But when I reviewed the datasheet of HMC-MDB277 again, it seems that HMC-MDB277 is preferred…

  • ERROR in ADIsimPLL flicker simulation for HMC parts

    There is a ERROR in the ADIsimPLL  for the HMC parts.

    The 1/f flicker specification for AD parts is made at 10 kHz offset normalized to 1 GHz.

    The HMC parts are specified at 1 Hz offset at a normalized frequency of 1Hz.
