• ADL5373 Output frequency range

    Hello,

    I'd like to confirm the output frequency range of ADL5373. According to the datasheet, the output frequency range is 2300MHz to 3000MHz. And the modulation bandwidth is >500MHz. Does the output frequency range include the bandwidth? (It can support…

  • ADL5373 S-Parameters File request

    From the ADL5373 datasheet page 11 says: "The balun presents high impedance to the output (VOUT); therefore, a matching network may be needed at the output for optimal power transfer". On page 7 I've seen the smith chart of the Vout S22 (Pin 13) from…

  • FAQ: Typo Error at ADL5373/4/5 datasheet

    There is a typo error at DAC Modulator Filter components at ADL5373, ADL5374(Fig32,34), and ADL5375(Fig 60, 63).

    C1I and CIQ should be at pF not nF. So they are 53.62pF and filter performance is as shown at datasheet(Fig33 at ADL5373/4, Fig61at ADL5375…

  • RE: Can AD9152 be connected to ADL5375?

    Hi

    There are two versions of ADRF6720. One is ADRF6720 that asks 0.5V common mode voltage and the other one is ADRF6720-27 for 2.7V common mode voltage. So ADRF6720-27 matches to AD9152.  Please refer to below figure 45 for two combinations of DAC and Modulator…

  • RE: Balun

    Balun is the common product to convert single-ended(un-balanced) signal to differential(balanced) signal or vice versa. Usually balanced differential driving give better performance at common-mode, even-order performance than single-ended driving and…

  • 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…
