Hi Sir:

 

We use 2 different version of ADL5331 in our project, but get 2 different result (Same input conditions).

 

Input 737MHz, -17dBm, VGA Gain = 7dB

We know A chip and B chip from 2 different packaging factory (Information from PCN).

 

May we know what different between these two?

 

Thanks and Best Regards,

Keven
