Hans ,? Jonathan says? -? "I am not even sure if a single resonant band pass filter is the best option for my use.."
This has some ambiguity? - does it mean a single resonant cct, one per band. ? That's marginal . SW Labs used that type of cct as the input to a mixer in many of their? ccts? (Dave Benson) years ago. It worked ok but was not state of the art. It only worked because it was backed by a Ladder filter further down the Rx chain. This sort of design only works with? a transformer input LC coil? ie it needs impedance transformation from the antenna? and it also needs to be decoupled from the forcing function as per all SHM resonators.
OR?
Does it mean a single filter with multiple resonant? band pass elements which sounds like a technical contradiction but is similar to your two band? LPF designs.?
FYI I sent him an old Arrl? design with three off? diode switched dual tuned? BPFs and a? bipolar? wideband booster at the far end.? THere is in fact a fault with the schematic x 3? which I pointed out to Jonathon.? If you want? Simple, buildable with no prototypes and decent performance, this is hard to beat.
