“…Real square signal looks like a trapezoid one. Architectures capable of delivering square signal to power amplification stage, like [2][3] [4] are then, theoretically, the best option to obtain highest efficiency values.…”

“…Most of these solutions, e.g. [2] [3], perform a transformation of high Peak to Average Power Ratio (PAPR) signals, issued of complex modulations such as OFDM, into constant envelope ones. The motivation of this approach is that constant envelop e signals could be efficiently amplified using a switching mode power amplifier, such as class E [4], which could, theoretically, attain 100% drain efficiency.…”

A class E power amplifier operating at 3. 7 GHz -one of the IEEE802.16e operating fre quencies -has been simulated using a LDMOS SOL BSlM3S01 model. Various driving signal waveforms were tested in order to determine which one leads to best class E performances. 8 7% of drain efficien cy and 74% of Power Added Efficiency (PAE) with gain of 8.3 dB was obtained providing a clipped sinus driving signal to the PA, from the best ofour knowledge, this is the highest PAE obtained at this fr equency using LDMOS transistor.
