Smile BPF / noise attenuator for TA7642 - improved design

Hi all! Recently I have found some new diagrams for the well known TA7642/LMF501. Here are presented some diagrams for band pass filter and at last an improved FET buffter with 2 tuned circuits.

*Please note that for the diagram from page 7 there is used a loopstick antena + 2 x red coils (MW oscillators) in series! The capacitor between those 2 tuned circuits is not necessary to use because of the internal capacity of the VC.

Is not copywright because I wrote the source page like wikipedia does. In fact the website could be broken after a while and then nobody could access the information.
