• HMC516  HMC564


    Can you please tell me if there has been any changes to the internal bond connections or pin out for the HMC516LC5 device? I recently received a batch where pins 25,27,29, and 31 are now grounded. The NC pins on previous parts were internally…

  • HMC564 Pin short

  • HMC564 RF input power doubt


           In the datasheet HMC564 V06.1017 , the RF input power is described as 5dBm,

           In the datasheet V08.0618, the value is +20dBm.  Does that means we have two different kinds of HMC564 or it's just one clerical error?  If there are two kinds…

  • RE: 2HD, 3HD data of HMC441-Die and HMC462-Die

    Hi HM,

    Unfortunately, we do not have the 2nd & 3rd harmonic data for these parts (or the IP2 data required to calculate this) at the moment.



  • why the S-parameter results of HMC564 datasheet and S2p file are quite different?


     I would like to ask why the  results of S parameters of hmc564 in the datasheet and the the simulation results by S2p file are  quite different.

    Hmc564 datasheet:

    Using ADS  to import S2p file  get  result:

  • ltc2641 die -

    The largest temp range the DAC will operate per the data sheet is -40 to +85 C. If I get the die will it operate at -55 to 125C? I will be mounting the die on ceramic substrate.

    does the assumption that it will work if properly heatsunk although the…
