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 center frequency abstains 6 MHz from the previous one center frequency and 6 MHz from the next one center frequency. In other words Each channel has a 6 MHz bandwidth.
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 because they cannot made for so high frequencies.
Next week I have to answer if I can design this circuit or not and I would like to know if there is any way to do it.
