Gain and return loss issue in ADL5324 default eval board

Hello ,

I have purchased a default eval board of ADL5324 as per below link and data given, this eval board works quite well in the 2.2 GHz to 2.3 GHz 

ez.analog.com/.../3704.ADL5324-2p2_2D00_2p3GHz.xlsx

But, data does not match with our purchased default eval board of ADL5324. please find attached file of measurement between 2.2 to 2.3 GHz

I have set VCC= 5 V. gain =11.87 dB, input return loss=4.42 dB and output return loss=6.74 dB  measured at 2250 MHz frequency.

Please provide guidance.
