Hi,
I'm trying to design a passive IF bandpass filter with the following specifications:
Center frequency: 61.38 MHz
3dB band width: 2.4 MHz
My first choice was a 3rd order butterworth/chebyshev filter but the attenuation isn't good enough, so I increased the order.
However, with the component's Q-factor that I have available, the insertion loss is just too big (10-15 dB).
Q inductor ~ 50
Q capacitor ~ 1000
Any way to design this filter with the components in hand to achieve a better frequency response?
Thanks for the help,
Alex
