Abstract
Embodiments describe improved coupling of power amplifiers to antennas for the transmission of signals, such as OFDM signals. A large number of separate windings are utilized on a primary side, wherein each winding is for a different OFDM tone. Each OFDM tone may be amplified individually and combined as a results of transformer coupling. For example, the secondary side can have a single winding that combines the different OFDM tones.
