Hi, I'm interested in how fast does the transfer function of the LFTX boards decreases after the nominal bandwidth of 30 MHz. I suppose, one of the key components of the LFTX is the operational amplifier (OP). Unfortunately, the exact OP used on the LFTX board is not given in the schematic (http://files.ettus.com/schematics/lftx/lftx.pdf) or on the corresponding website (https://kb.ettus.com/LFTX/LFRX). There, I can only find the ADC driver for the LFRX, but it seems that they are different. Does anybody know, which operational amplifier has been used so I can look into the data sheet. Best regards Benjamin

Moin Benjamin, it's an AD8047; certainly a bit oversized when it comes to gain·bandwidth considering the low pass configuration, but still a pretty standard Opamp. Maybe you can share with us (or support@ettus.com) what you're underlying questions are?
