A novel inverse class E power amplifier topology

In this work, a 10 Watt inverse class-E power amplifier has been proposed, simulated, realized and measured for the 2.7-2.9 GHz wireless applications. In the proposed power amplifier topology distributed elements were used instead of lumped elements and their widths and lengths were optimized with AWR Microwave Office. The new architecture showed 80% power added efficiency and 10W output power during the measurements. All of the harmonics up to 5^th are 40 dB lower than the fundamental component. These measurement results are the highest reported in the literature over the 2.7-2.9 GHz frequency band so far.
