Restarting an older thread....
I'm trying to move the cutoff frequency of my 15/17 LPF filter on my QMX 60-15 about a MHz higher. I tried modeling it in Elsie, but it looks nothing like a LPF.
What should I be using for Zin and Zout ?
Besides the basic filter made up of L510, L513, C516, C519, C525, are there other components I should be including ?
Thanks and 73,
Steve, N2IC
