Understanding of OIP3

Hi

I have a question about OIP3 of ADL5535.
Datasheet says that OIP3 is 45.5dBm at 190MHz and 380MHz. Is this indicated as the total power of two-tone ?
And the attached file shows my understanding.
Please find attached file, and let me know my understanding to be correct or not.

My concern is the power to be defined as total power or each power.

Best Regards,

  • Hi jdobler

    Thank you for your reply.
    I have a question from the customer about this.
    His evaluation result of ADL5535 is that OIP3 is 42dBm per tone in 340MHz.
    Although I doubted the definition of per tone or total power, your reply has made it clear.
    But I find the difference between datasheet and his evaluation result. Datasheet says OIP3 to be 45.5dBm.
    Can you share your comments about this difference ? 
    Measurement, calibration, unexpected distortion, distribution and others.

    Best Regards,
