2.45 GHz Class E Power Amplifier for a Transmitter Combining LINC and EER

M. Dirix, O. Koch

Abstract


A 10 W class-E RF power amplifier (PA) is designed and fabricated using a Cree GaN HEMT. The proposed PA uses an innovative input circuit to optimize band with. At 2.45 GHz the PA achieves a PAE of 60 % at an outputpower of 40 dBm. The resulting amplifier is simulated and constructed using a transmissionline topology. Two of these amplifiers are fabricated on a single board for outphasing application. Their suitability for outphasing application and supply modulation is investigated.
