I've never really heard the term stop band used for a BPF. Are you trying to make an active or passive filter? What order filter do you need, how fast does the pass band have to roll off?

Then you can determine the filter order. I've never really heard the term stop band used for a BPF. Click to expand... Every filter (except for all-pass) has a stop band. Also presume a passive filter for x GHz.

Click to expand... Means 0.45 GHz transition band, stop band corners 3.05 and 6.95 GHz? How about pass band ripple?
