The new Butterworth seems to work quite well |
|
|
It works better probably because of the small inductors I'm using this time.
The peak is at 30 MHz because I didn't have the precise elements to get 33.
The bandwidth and the Q could be improved by adding one or two more order to the filter and trying to better match the low-pass' resonant frequency with the high-pass'.
Also I have to see if it could work at 166 and 199 MHz as well. |
