Band pass filter [(10)CN101335506B]

[Category : - ELECTRONICS]
[Viewed 89 times]

The invention discloses a band-pass filter which comprises a plurality of inductors and a plurality of capacitors. One end of a first series capacitor is electrically connected to one end of a first series inductor. One end of a second series capacitor is electrically connected to the other end of the first series capacitor. One end of a second series inductor is electrically connected to the other end of the second series capacitor. One end of a branch capacitor is electrically connected to one end of the first series inductor, while the other end is electrically earthed. One end of a second branch capacitor is electrically connected to the other end of the second series capacitor, while the other end is electrically earthed. One end of a central capacitor is electrically connected to the other end of the first series capacitor, while the other end is electrically connected to earth. One end of a central inductor is electrically connected to the other end of the first series capacitor, while the other end is electrically earthed. One end of a central inductor is electrically connected to the other end of the series capacitor, while the other end is electrically earthed. The elements above form a prototype circuit. In the prototype circuit, at least two of the plurality of elements interact with each other for creating at least one mutual capacitance or at least one mutual inductance which forms a resonance circuit with the prototype circuit for creating at least one transmission zero used for speeding up forbidden band attenuation rate.
