Abstract

The inter-modulation distortion products vary in amplitude and asymmetry due to the effects of baseband and 2nd harmonic impedance. This paper presents an investigation into the relationship between the IMD asymmetries caused by baseband impedance variations and looping or hysteresis that can sometimes appear in the dynamic transfer characteristics of microwave power devices when subjected to modulated excitation. Here, the investigations are carried out on 2W GaN HFET bare die device characterized at 2.1GHz, and using IF active load-pull to quantify the role of baseband impedances on observed hysteresis in the dynamic transfer characteristics. Analysis is performed in envelope domain in order to more effectively reveal the DDT's sensitivity to electrical baseband memory effects.
