Abstract

High-breakdown and high-linearity Ga_0.51In_0.49P/In_0.15Ga_0.85As pseudomorphic HEMT's have been fabricated successfully and demonstrated. A extremely high gate-to-drain breakdown voltage of 40 V is obtained by using a wide-gap Ga_0.51In_0.49P Schottky contact layer. For a 1 μm-gate length device, the transconductance and output current density at room temperature are 90 mS/mm and 646 mA/mm, respectively. The measured f_T and f_max are 12 and 28.4 GHz, respectively. Therefore, the studied device shows a promise for microwave power applications.
