• ADL5375 modulation method

    How's ADL5375 modulation method is I (t) * cos (2 * PI * ft) - Q (t) * sin (2 * PI * ft), or the I (t) * cos (2 * PI * ft) + Q (t) * sin (2 * PI * ft)?

    And how to determine?

  • RE: DAC-adl5375 dc coupled interface & LOFT optimization

    Hello sdh,

    A review of the ADA4932 datasheet shows that common mode errors are intended to be reduced.

    In order for LOFT nulling to be accomplished on the ADL5375, offsets need to be intentionally introduced on each pair. For example, I channel offset…

  • ADL5375-05 harmonics


    I'm testing ADL5375-05 modulator on ADL5375-05EP EVALZ evaluation board and I'm getting higher order harmonics significantly higher then specified.

    The test I did is replica of the datasheet test at 2.15 GHz and 3.5 GHz. The LO is single…

  • CN0285(ADL5375+ADF4351) Modulator testing issue


              Customer use CN0285 EVB for OIP2 test by below condition.  They compare to ADL5375 datasheet that OIP3 under reasonable range as Figure 18. But OIP2 test value looks worse compare Figure 19. What are difference between datasheet testing condition…

  • RE: ADL5375 noise floor

    Hi Dragan,

    The LO source phase noise is often the culprit in these situations. Note that until now we have been discussing noise floor in terms of dBm/Hz, whereas phase noise is usually relative to a carrier signal in units of dBc/Hz.

    It's difficult to…

  • Impedance matching when AD9717 or AD9779A interfaced with ADL5375

    Can you confirm why I need to use 500ohm or 50ohm impedance matching for the
    AD9717 and AD9779A interfaced to ADL5375.
    Sorry for that basic questions, but I am from the digital world.



    Remember, that the AD9717's and AD9779A's output and ADL5375…

  • RE: operation of ADL5375

    The ADL5375 needs the common mode voltage to operate correctly. This is very common with IQ modulators, as it provides a means of carrier LO nulling. It sounds like you might need just a normal mixer. Take a look at the product search link below. Possibly…

  • ADL5375-LO input Amplitude and phase balance limits


    I want to apply differential LO input to ADL5375 using a balun which is used for converting single ended LO from RF PLL to differential. The balun shall have amplitude and phase unbalance,

    What is the acceptable LO input amplitude and phase unbalance…

  • LO Bleed-through with ADL5375


    I have a single ended signals transmitted from an AC coupled DAC. The DAC has 4 outputs and I am using 2 of the outputs as I and Q (90 degrees offset).  In order to drive the ADL5375-15 modulator with a DC biased differential input I am using  2 x DC1147…
