ADL5811 connection with ADL5387

Question

In our design, we need to use both ADL5811 and ADL5387 evaluation board. Firstly, we would like to use ADL5811 evaluation board to convert the measured signal to an intermediate frequency IF. Then this IF signal is mixed down to I and Q signal by ADL5387 evaluation board. Thus, we connect the IFOP port of ADL5811 to the RF port of ADL5387. Unfortunately, we found the issue for this connection. When we added the power supply to ADL5811 evaluation board, this caused the short path between the power supply and ground of the ADL5387 evaluation board. Would you please help us resolve this problem? Can we directly connect ADL5811 and ADL5387 together? 
 
 Thanks.
