| 1. A power amplifier system comprising:
a power amplifier that generates a first differential output signal and a second differential output signal;
a primary winding comprised of a plurality of primary segments, wherein a first end of each primary segment is connected to
a first common input port and a second end of each primary segment is connected to a second common input port, wherein the
first common input port is operative to receive the first differential output signal, and wherein the second common input
port is operative to receive the second differential output signal; and
a single secondary winding inductively coupled to the plurality of primary segments.
