Hello I am designing an fm receiver and had some questions about the RF front end. To tune into different channels I know I need a tunable oscillator, but does the bandpass filter connected to the antenna also need to be tunable? or just have a bandwidth of 200MHz. I don't really have any circuit schematics ready yet to share sorry. Also, it may be a stupid question but I also wanted to ask if the image rejection filter and preselector are the same or not.
