• How is delay of ADL5372 of I/Q to output if I work at 2.4GHz?

    I am planning use a quadmod; however, I am concern about its delay. How is much is the delay on I/Q path to output for ADL5372? Kindly let me know.@

  • Query about ADL5372's Output Power Variance

    Hi, there

    One question needs your help: Where is test point of Output variance plot in figure 5 of your datasheet ADL5372? Or how is the plot obtained? Looking forward to hear from you soon.

    Thanks!

  • RE: ADL5385 top end wiggle room

    It was designed and characterized upto 2.2GHz.  No data to show the performance above 2.2GHz and  so can't say a specific number for the top end frequency since we have not characterized fully.  There would be performance degradation including output…

  • FAQ: Measuring the Compression Point (OP1dB) of IQ Modulators

    Q.

    Could you please tell me how we test the P1dB of an IQ Modulator like the ADL5375 or ADL5370/1/2/3/4? Since the P1dB is so high, how do you apply a baseband signal of such a high high level?

  • FAQ: When I use the Auxiliary DACs to compensate for IQ Mod LO Leakage, what resistor tolerance should I use?

    Q.

    I want to use the Auxiliary DACs of the AD9779A to compensate away the LO Leakage of an IQ Modulator. I am using the recommended schematic from the data sheet of the ADL5370/1/2/3/4 family of IQ Modulators. What resistor tolerance should I choose…

  • Temperature Drift of IQ Modulator LO Leakage after Calibration at 25 degC

    Question: In the attached plot (labeled Figure 10) from the ADL5375 IQ Modulator Datasheet,  LO Leakage degrades significantly vs. temperature at higher frequencies after compensation at 25 degC. What is going on here?

    Answer:  It is important to understand…
