Patent ID: 7812701

Claim:
A system for multiple transformers, comprising: a first transformer that includes a first primary winding and a first secondary winding, wherein the first primary winding encapsulates the first secondary winding, wherein the first primary winding is inductively coupled to the first secondary winding, wherein the first transformer is associated with a first rotational current flow direction in the first primary winding; and a second transformer that includes a second primary winding and a second secondary winding, wherein the second primary winding encapsulates the second secondary winding, wherein the second primary winding is inductively coupled to the second secondary winding, wherein the second transformer is associated with a second rotational current flow direction opposite the first rotational current flow direction in the second primary winding, wherein a first section of the first primary winding is positioned adjacent to a second section of the second primary winding, wherein the adjacent first and second sections include a substantially same first linear current flow direction, wherein one or more of the first primary winding, first secondary winding, second primary winding, or second secondary winding include a respective center tap port, wherein one or more of the respective center tap ports are connected to respective tuning blocks to adjust frequency characteristics of the first transformer or the second transformer, the respective tuning blocks comprising a respective combination of at least one inductor and at least one capacitor.
