Re: [Openbts-discuss] How to remove ISM-band filter on RFX900?

[Sylvain M. <24...@gm...>]

You actually don't need to remove it.

1) Cut the traces to and from the ISM. Make sur to cut them right as
the angle so that the remaining traces look like a single straight
line.
2) Solder a 10 - 100 pF cap in the empty slot parallel to the ISM filter.
