Change inductor on ADL8122

Heymqiah1, 

The performance between the custom inductor value and the default inductor appears to be similar. However, I am concerned that the footprint differences between these parts may lead to compatibility issues.

Hi thank you for your fast reply!
In this schematic i added the footprint for a rough comparison:

I would design my own PCB with matching footprints if that is what you meant with compatibility issues. 

What do you think would be the worst case if i try the following:
I use this smaller inductor component (LPS4040 68uH), but i i introduce 0ohm jumper to use or short out the (680uH || R300ohm) and leave these components unconnected:

pads for potential 0 ohms marked:

In principle this should be similar to the 2nd EVAL-board with a higher lowfrequency cut (100kHz -> ~10MHz)?

Thank you!

Based on what you proposed, the 0-ohm jumper approach appears to be a more practical and effective in this application.

Dear mqiah1 ,

did your solution work eventually? 
If yes, could you share the bias tee layout you did? 

Kindly,
