Original question:

ADC32RF45: Input s-parameters or input impedance

ADC32RF45: S-parameters and SBAA219

Part Number: ADC32RF45

Hello,

I read the above Application Report regarding S-parameters for the ADC.

Q1. Page 6 states to use a 1:1 transformer to convert the differential impedance of the ADC input to single ended for the S-parameter model.  But the model is defined as differential by default; why is a transformer element is used? Is it the case that the measured impedance of ADC is single-ended?

Q2. Page 10.  The report state to use a 1:1 transformer to transformer but the ADS schematic uses 2:1 transformer.  Why is that? How is it calculated?

    Hello,

    I downloaded the single-ended S-parameters from the forum related to ADC32RF45 and simulated the impedance.

    At 1.82GHz, the impedance (reference to 50 ohm) is 50*(0.216+j0.237) = 10.8+j11.85. Magnitude Z is about 16 ohm.  So for differential, the impedance is 2 times the Single Ended as 32 ohm differential (c.f. App Note, 25 ohm differential)

    Q1. Why is there a difference between the measured S-parameters and the App Note?

    Q2. Which one is correct?

    Hi Maxplus,

    Q1. Page 6 states to use a 1:1 transformer to convert the differential impedance of the ADC input to single ended for the S-parameter model.  But the model is defined as differential by default; why is a transformer element is used? Is it the case that the measured impedance of ADC is single-ended?

    Ans: All S-parameters mentioned in the report are 'differential mode' quantities. To ease the understanding of the model, the 'DD' sufix is not added. SDD11 is mentioned as S11. The transformer element is used to get differential input from single ended S-parameter model. 

    Q2. Page 10.  The report state to use a 1:1 transformer to transformer but the ADS schematic uses 2:1 transformer.  Why is that? How is it calculated?

    Ans: The transformer used is 1:1 for each differential side. It is used here because differential 100 ohms reference is used here. This is explained in Figure 14. From Table 2, we can see what component values are used for differential 100 ohm (calculated from an assumed single ended 50 ohm system) 

    Regarding the mismatch between values from app note and S-parameter file provided, I have reached out to the team who made the app note. Will update you in 2 or 3 days.

    Regards,

    Vijay

    Hi

    The s2p block of the ADC is measured in 50 ohm single ended. The reference differential impedance is 100 ohm for ADC. Therefore impedance transformer N should be 1.414.  Why is it to 2?

    Hi Maxplus,

    Please find the attached differential S-parameters (S11dd) mentioned in the app-note. To design matching circuit, please use this file instead of the S2P block you downloaded earlier. For simulation, you can follow the method described in the app note as it is proven.

    Hi

    Thank you.

    I will look into this. As the S parameters are in differential mode, is my understanding correct that impedance transformers are not required.

    Hi Maxplus,

    You are correct. Impedance transformation is not required.
