• HMC1061 and HMC661 thermal resistance


    Can you provide the junction-to-case thermal resistance (both top and bottom) of HMC661 and HMC1061?

    Thank you.

  • RE: Configuring phase relationship between two outputs of HMC7044 with Analog fine delay feature

    Thank you! Nice answer! Many datasheets say that analog delay may cause some phase noise degradation. Do anyone know how much is this degradation? how much will it increase jitter? In my application i want to clock track and hold amplifier hmc661 with…

  • T&H IC Sampling Speed for HMC5831

    Dear Sir,

    I have one more question.

    HMC5831 provides 26 G-sampling per sec operation,

    however, I can’t find the ultra-high speed T&H IC that can support 25G-sampling per sec on HMC5831.

    The fastest I have found is HMC661 or HMC5640 that specifies…

  • RE: Clock frequency of HMC661LC4B

    The HMC661 device has minimum clock frequency of 250MHz as specified in the datasheet. If you clock it at a lower frequency, and 50MHz is lot lower than 250MHz, the droop will be too severe and some datasheet performance specs will be violated. So we…

  • Wright Brothers Appreciation Day

    In anticipation of Wright Brothers Appreciation Day, we reached out to a few of our engineers who also log time flying the fair skies. Here’s what they had to say about aviation, ADI, and the legacy of the Wright Brothers.

    This part is EAR99. The attached RFIC selection guide lists the ECCN codes for all of ADI's RF products.


  • RE: 36GHz RF oscillation signal source

    You need a PLL which drives a frequency doubler which drives an amplifier. Possible choices might be ADF4371 (PLL),  HMC1105 (frequency doubler) and HMC7229 (amplifier). These are not the only choices.
