Hey guys,
So I have been running some simulations where I am creating a BPF around the FM band and when I measure the signal on the output, it's much lower than my original signal. So I thought if I put a buffer between the LPF and HPF to electrically isolate the circuits this would help, but it didn't appear to be any improvement. In fact it just seemed to make the output look more "messed up". My only guess is that the buffer I am using (LT1395) is not fast enough? Any ideas?
Does anyone have any favorite high speed op amps (buffers) they use for the FM band (~100 MHz) or above?
Thanks
