OK, I am admittedly L. A. M. E. when it comes to circuit design. I was hoping that I could find a simple tool to help design a 5 or 7 pole filter. Hell, I'd even start with a 3 pole filter and then go from there. Using any of the tools I've found so far, I can get various designs fairly easily. However, they always come out with capacitance values that you'll never be able to find. It also seems like you have to use trial and error with the inductance calculators to come up with the right size air wound coil. Is there a tool somewhere that can make this a little simpler (especially since I'm math lazy)? I'm not even trying to worry about impedance matching at this point...i'm just assuming 50ohms in and 50ohms out.
