Problem of getting downconverted IF signal from ADL5387 eval board

Hello,

 

I recently purchased an eval board of ADL5387 IQ downconverter. However, I encountered some difficulties getting out the mixed IF signals. My RF frequency was 900MHz and my LO frequency was 930MHz. Both LO and RF power level was 2dBm, within the recommended range. But I could not detect any signal at 30MHz using spectrum analyzer. Does anyone have the same problems?

 

Many thanks.
