ADRV9002_Noise floor rise at higher freq


In ADRV9002, noise floor and side band noises are increased when increasing the frequency and power level.But in lower freq,  noise floor and sideband noises are less. For Ex compared to 200MHz spectrum , 2GHz , 3GHz noise floor (approx 20dB rise) and side band noises(approx 10dB rise in +/-1Mhz offset) are increased at higher power level.  Pls refer the attached test report images which is taken from EVM board. Same test cases are implement in our module and same response was observed. Pls give the solution for this issue.
