I don't have any problems with rotating the inductors, after all, that is
one of the best way
I came across this filter design recently and thought I'd build a few.

I was about to place a Mouser order when I came across someone selling
filters, based on the above design.

isolation between them is not a good idea. The resulting transfer function will

I thought I'd put one on a FE-5680A and see what happens to the third
harmonic. It might also be interesting to see if I get a decent sine
wave out of the filter with a square wave in.

Based on that PCB, I want to see an sweep to at least 1GHz.

Hi
The standard FE-5680 very much has an LC filter between the output amp and the
output pin. I'd take out their filter and put this one in. I would not use both
together.
