hello
i would like to know how to design asymmetric
filters.

Hi
ofourquin
In what sense are they to be asymmetrical?
Impedance
unequal at input and output?
Or unequal roll-off slope LF side vs
HF side?
Bandpass, low-pass, or high-pass, or any?
There are
some good websites that include java script routines for interactive
filter designs.

hi
I would like to do a band
pass filter
It is the structure of the filter which is not symetrical.
It is also call coupled filter in “Handbook of Filter Synthesis” books
from Zverev.
The impedance is set to 50 Ohm in input and output
for UWB applications [3.1 ; 10.6] GHz.

Just a precision
it is not bandpass filter based on the LP filter theory where
where we find capacitor with a inductance in series
ps sorry
for my bad english
