Hi gang,
We are using Coilcraft conical inductors for bias tees.
http://www.coilcraft.com/pdfs/bcl-s_.pdf
There are a lot of them on the board, right next to each other. A rule
of thumb I've used for inductors is to place them at 90 degrees from
each other, this is supposed to reduce mutual inductance, assuming the
inductors are the cylindrical coil type.
How do conical-wound coils interact? I think these are air-core
although the units I have have some sort of plug that the coil is
wound on, I don't know what it is.
I'm also guessing that coils placed on top and bottom of a standard 60
mils thick FR-4 PCB with two ground planes will still couple
magnetically, right?
Thanks in advance.
