How to remove the impedance match on ADL5580 EVALUATION BOARD

Question

Dears, 
 I bought a ADL5580 EVALUATION BOARD to evaluate the performance. 
 However, it is mentioned on ADL5580 user guide that there is a resistive impedance matching converts the 50 &Omega; differential output to a 100 &Omega;, which adds 7.7 dB of attenuation. 
 I'm wondering how to remove this impedance matching because the output of ADL5580 connects to a 50 &Omega; differential load for my testcase. 
 Your suggestion is appreciated.

Hi aarontang, 
 You can remove resistor components, R4, R5, R6, and R7, which are used for the matching and wire from a differential output signal trace to your test board. 
 
 Thanks,)
