Abstract

A magnetically coupled bandpass filter, in which the coils are in the same plane, characterized in that the tuning or damping elements (or both), such as ferrite cores, damping plates, etc., are out of the coil and close to the point of greatest strength of the field, whose members primarily influence only one or the other of both halves of the filter bandpass feature on either side of the medium frequency, or having a conductor, so less, coupling at the current or voltage crossing points with which the coupling is effected or damping means, or more than one of the mentioned means, with influence, primarily, on only one or the other of the halves of the pass-band characteristic of the band-pass filter.
