A Realizability Test as Applied on the Generated Source/Load-Pull Data
Generation of proper source/load pull impedances for a selected active device is essential to design an RF power amplifier for optimum gain and power added efficiency. As they are obtained, these impedances may not be realizable network functions over the desired frequency band to yield the input and the output matching networks for the amplifier. Therefore, in this paper, we introduce a useful method to test if the generated source and load pull data are realizable. The proposed technique is employed to test the given source and load pull impedance data obtained from the 45W-GaN power transistor of Wolfspeed “CG2H40045” over 0.8-3.8 GHz bandwidth.
