Control del comportamiento en distorsión de intermodulación en un pHEMT de enriquecimiento

Abstract

In this paper, an Enhancement-mode Pseudomorphic HEMT has been characterized in terms of its intermodulation distortion behaviour. Small-signal parameters are extracted using a laboratory characterization procedure and applying Volterra Series analysis. We have also studied large-signal IMD3 performance, particularly taking the linearity sweet-spot behaviour into account. The potentialities of this device for highly linear applications have been remarked.
