this bandpass filter designed has this response and pretty much behaves like this when breadboarded
there is only one exception - the output doesn't jump to 45dB as spice is saying but that wasn't expected in the first place -> it goes up to about 10dB
there is a problem though
you can't load it with either a bjt based voltage voltage follower (2n3904) or a diode (1N4148) without killing the signal
i don't have other components atm, it's clearly an impedance problem but idk why voltage follower isn't working
for the diode literally have no idea why it won't pass a signal - it has a 1v forward voltage but the signal is 4Vpp so something should pass. raising the DC level of the signal doesn't help either
