Dear all,

I am a beginner in filter design, pls help.
I am designing a butterworth bandpass filter using capacitively coupled resonator.

i using 2 resonators,
1 coupling capacitor C12,
1 input coupling capacitor C1,
1 output coupling capacitor C2,

Is it the the capacitors in the two resonators same value? which is
Co- C12- C1 = Co- C12- C2 ??

If not, pls give some advices. Thanx a lot.

In general, the shape of the curve varies with the value of C12. Its value depends on the loaded Q of the two resonators.

More later.

Good Luck
