A novel inverse class E power amplifier topology
2013 21st Signal Processing and Communications Applications Conference (SIU), 2013 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.
