• RE: S2P file of HMCALH444

    Hi Maria,

    Below is a plot of the HMC-ALH444 noise figure vs. frequency grouped by operating temperature and DC bias. Because the HMC753LP4E is our packaged version of the HMC-ALH444 die, I've also included the noise figure plot from the HMC753LP4E data…

  • HMC-ALH444-SX and HMC-ALH444 difference

    Hello, dear all!

    please, could you clear a difference between HMC-ALH444-SX and HMC-ALH444


    There are no inform on the www.hittite.com.


  • HMC-ALH444


    Do you have any performance data or plots vs. temeperature for the HMC-ALH444 Die? I need to operate over an ambient temperature range from -20 to +70 and would like to know how the device will perform. Thanks.

    Best Regards.

  • [Urgent] Channel Temperature of HMC-APH403-DIE


    Our customer requests the channel temperature data of HMC-APH403-DIE. Could you please let me know ?

    He compares HMC-APH403-DIE with a competitor. If he takes the data quickly, there is some chance of beating.



  • RE: Board level alternative to HMC-C019


         The HMC-C019 consists of 2 HMC547 die in series.   As long as you optimized the layout for isolation there is no reason a PCB version of the HMC-C019 should not work as well.

    best regards,

    Please create separate posts requesting die dimensions for the following products:




    BTW, each datasheet has figures with die dimensions and bond pad locations.

  • RE: HMC-C009 Design issue

    The HMC-C009 uses the HMC525 die.  Best advice is to ensure the Phase length  of IF! and IF2 are matched.

    Find both Q&A below. 


    1. We only show decoupling for one side of the die. The top side in the view
    below has the same supply pads. Is decoupling only on one side required and can
    it be either side?
    Yes the supplies only on south or north…
