• RE: HMC-ALH509- Vacuum and Plasma?


    The HMC-ALH509 can be plasma cleaned.  The air bridges are part of the GaAs HEMT fabrication process.  When you ask about vacuum, are you referring to picking the die with a vacuum tip?  The air-bridges are fairly robust but can be damaged if not…

  • HMC-ALH509 - Bypass Capacitor


    I would like to use the same or similar capacitor that Analog Devices recommends for the 100pF and 0.1uF bypass capacitors. Can you recommend, type, make and model of the capacitor used?



  • RE: LOW drain current (AUH320, ALH509, HMC1144)

    Hi Jaber,

    I support the HMC1144 and can answer regarding that product, though I support neither the HMC-ALH509 nor the HMC-AUH320 and thus cannot answer for either of those products. The applications engineer(s) who support those products should soon…

  • [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: HMC-ALH509 square pad, what size?

    Anyone get a chance to look into this?  I think you might be able to help me out with this?

    Basically I want to draw the die in ADS, and the dimensions are very important for me in order to get the connections right... The datasheet isn't clear.…

  • 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,


  • RE: I am building Footprints for our Library and am looking for DXF files.

    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.

  • HMC-ABH241 : Die Related- Queries

    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…

  • RE: HMC-ALH364 and HMC-ALH476
