Super Band notch filter

Hi there,

I would like to buid a notch filter for any of the CATV channels 31 - 39. The band frequencies for these channels are from 573.25 to 621.25 MHz. Each channel abstains 6 MHz from the previous one and 6 MHz from the next one.

I have found that I cannot use coils beacause of their low Q for this notch filter, I have also found that I cannot use quartz filters fecause they cannot made for so high frequencies. So what the hell I could use?

Next week I have to answer if I can design this circuit and I would like to know if there is any way to do it.

Please Help,

Thank you.
