Abstract

In this paper a comparison between classical Class E and new Class FG power amplifier design strategies are presented,to evaluate which method is best suited for high efficiency performance when operating frequency lies in the low microwave range.Fundamental design guidelines are briefly discussed and the Class E strategy is critically revisited with a frequency domain approach,stressing the differences with the Class FG.Finally,in order to validate the analysis,measured performances of a realised Class FG PA will be presented and compared with the simulated results of a Class E PA.For the same operating conditions,Class FG amplifier exhibits superior performances,with a maximum PAE of 59.8%(measured 58.8%)and a saturated output power of 25dBm,compared to 48%and 24dBm of Class E.Moreover,the 1dB compression point is 3dB higher for the Class FG.
