ABSTRACT:
A filter device may include a plurality of ferrite filters laminated together in vertically stacked relation, where each ferrite filter may include a pair of ferrite layers laminated together in vertically stacked relation and a lateral conductor extending therebetween. The filter device may also include at least one vertical conductor connecting the lateral conductors together in series. Moreover, at least some of the ferrite filters may have different operating characteristics. In particular, the different operating characteristics may be different impedance versus frequency characteristics to thereby broaden an attenuation frequency band of the filter device.
