So I'm just wondering what I need to figure out before I can actually calculate anything here, (only considering the a-part now)? I understand that 2.5 GHz should be 3dB and 3.75 GHz should have 25 dB of gain, and if it's overshooting the specifications, but I'm not at all sure how I can calculate this.
I'm guessing that I'll need to figure out an actual equation for the filter, but I'm also clueless on what principles I should try to use here. Any pointers on what direction I should be headed would be cool.
Should I apply normalized low-pass prototype element values even though I've already been given the component values, or do I want to use that to compare if the components are overkill (assuming they work)?
