• Hittite HMC247 Analog Phase Shifter

    Hello... We have a couple of quite urgent questions on the Hittite HMC247 Analog Phase Shifter

    which we are considering for a new design.

    A) Can RFOUT be used as input, and RFIN as output?

    B) Can you please provide testing diagram of the control voltage…

  • Using HMC247/877 at 3GHz ?

    Hi, I am looking for an analog phase shifter on 3GHz, and I see ADI has two analog phase shifter IC HMC247 and 877.  But the listed lower frequency limit is 5GHz for one and 8GHz for the other.  My question is if I could use the devices on 3GHz at all …

  • HMC247 Phase vs. Voltage Curves

    Is there I can get sample curves of phase shift vs. voltage for various frequencies? The "Phase Shift vs. Control Voltage" figure in the data sheet would be sufficient!

  • Analog Phase Shifter control voltage? HMC-C010 and HMC247


    I'm a little confused about the description in the datesheet. It says the the phase is "controlled via an analog control voltage ". However, the provided data sheet gives the performance at with DC control voltages only. The control…

  • RE: ADMV8818 in die form?

    Unfortunately, the ADMV8818 can not be offered in die form.

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


    Could you share the 2nd and the 3rd harmonic distortion data?

    If there is no data of these products, something of the same product series is also fine.



  • RE: HMC985A-Die rf pins interchangeability


    HMC985A-Die can support bi-directional operation, however, the power handling for RFOUT might be lower than RFIN.

    The absolute max RF input power for HMC985A-Die is 30dBm as listed in the datasheet, therefore, I think it is OK to apply 15dBm max to…

  • HMC985 die

    Does anybody know why the HMC985 die has metalization on the edge?


  • 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…
