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 and CN0285?
Have OIP2 test results for CN0285 EVB to clarify the issue? Thank you.
