CPC H03H 9/542 (2013.01) [H03H 9/205 (2013.01); H03H 9/547 (2013.01)] | 19 Claims |
1. A filter comprising:
a first impedance path between an input node and an output node, the first impedance path comprising a first impedance and a second impedance serially connected to one another and defining a first node therebetween;
a second impedance path between the input node and the output node, the second impedance path electrically parallel to the first impedance path, the second impedance path comprising a third impedance and a fourth impedance serially connected to one another and defining a second node therebetween, the first impedance path and the second impedance path comprising a reversed semilattice filter;
a first inductor coupled the first node;
a second inductor serially coupling the first inductor to the second node; and
a resonant circuit associated with the first inductor and the second inductor, the resonant circuit configured to lower a common mode impedance for the filter at a predetermined notch frequency.
