How to bypass the filter on RXF2400 daughterboard

Hi, all!!!

I have read the manual of the RXF2400 and noticed that there is a filter
restricting the receiving bandwidth to be within ISM bandwidth. But in
our case, we need to work outside 802.11 band to avoid interference from
802.11, how can we bypass that filter using software? Thanks a lot!!!

I believe you must make a hardware modification if you plan on
bypassing the filter.

Thank you for so quick reply, Brian!

Making modification on HW is not what I can do. My case is like this: I
am transmitting 1Mbps data with center frequency set to 2483.5MHz. Do
you think it is doable without bypassing that filter (still receiving my
data without amplitude distorting)?

Thank you!
