1. A power amplifier system, comprising:
- a plurality of differential power amplifiers, wherein each differential power amplifier includes a respective positive output and a respective negative output;
a plurality of primary windings each having a first number of turns N1, wherein each primary winding is connected to a respective positive output and a respective negative output of a respective one of the plurality of the differential power amplifiers; and
a single secondary winding inductively coupled to the plurality of primary windings, the single secondary winding connected to a load, wherein the secondary winding includes a second number of turns N2 greater than the first number of turns N1, wherein the plurality of primary windings and the single secondary winding define a voltage-boosting transformer, the voltage-boosting transformer configured to increase voltage from each of the primary windings to the single secondary winding,wherein the primary windings are placed substantially in parallel, and wherein the primary windings and the single secondary winding are interweaved such that the single secondary winding is placed between the primary windings to provide that one primary winding does not substantially neighbor another primary winding.
