I would like to design an RF notch filter for allowing or not a TV channel's signal in a TV tuner. I have found some smd (1206 package) inductors (nH) from TAYO YUDEN company and I would like to use them.
I dont't have any experience in the RF design. So, is there anything I have to know or carefull about. I mean any tips???
Use an external filter with helical notch externally because if you implement this filter with conventional SMD components ( at especially higher frequencies) the bandwidth of the filter will be relatively large due to low Q factor of the components that you intend to to use.So that, this large band will also attenuate adjacent channels which are maybe desired to receive.
A channel notch filter should have very sharp bandwidth edges and high quality factored components.
This is not very easy to implement with SMD components..
