Direct Coupled Resonator Bandpass Filter Designer
IN OUT

REQUIREMENTS
Center Frequency [MHz]
Bandwidth [MHz]    
Passband Ripple [dB]   (0...6)
Number of Resonators    
Impedance [Ω]
Inductance  



* If the Ripple is 0 dB, a Butterworth Characteristic results. If larger : Chebyshev.


DESIGN DATA FOR YOUR BANDPASS

If you want to build a filter like this one, we highly recommend, that you simulate the amplitude response first ! Due to the capacitive coupling, the attenuation above the passband is rather poor if you choose the bandwidth too large. We suggest to start with a bandwidth not larger than 10 %.
