  • HMC-493 and HMC-492 self oscillation


    I'm using the HMC-493 (divide by 4) and the HMC-492 (divide by 2) in an application such that they don't always have RF applied to their input.  I've just read the app note "Frequency Divider Operation and Compensation with no input signal…

  • Questions for the battery (HMC-T2220、HMC-T2240 )

    We would like to export the Signal genetor of HMC-T2220HMC-T2240.

    If these SG have a battery (Lithium Ion Battery: re-chargeable) or Lithium battery (Coin battery) , they might be prohibited to export.

    Then could you tell us the HMC-T2220HMC-T2240 has…

  • HMC 751 LNA Testing

    Recently I have requested a sample of HMC 751 LNA with the complete evaluation board from Analog devices that operates from 17-27 GHz with a stable gain of 25 dB. Do i need any additional components to test it? Or I can measure it directly with the VNA…

    Could you kindly let us know what difference with AD2428WCCSZ and AD2428WCCSZ01?

    Our customer use AD2428WCCSZ01 first, but they want to modify to non-automotive version, but AD2428BCPZ no die revision, they confuse about it.

  • differential interference analysis using HMC 702 and HMC 584


    I am conducting differential interference analysis using HMC 702 and HMC 584, but there is a problem.
    The sign of the phase is changed by turning on / off the power supply.
    My question is

  • Same s parameters for HMC 370 and HMC 369

    The s parameter files of HMC370 and HMC369 are same. Even though the file names are different the content is the same that of HMC369. Can you please upload the actual S parameters file of HMC370

  • RE: HMC-ALH369 applied with photo diode

    I'm not familiar with this mode for operating an RF amplifier. I did some google searches which suggested that the 50 ohm input impedance of the RF amplifier is too low to act as a current to voltage converter (i.e. Vin(ac) = Iin(ac) * 50 ohms).  It…

  • 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…
