Depletion-mode GaInAsP/InP junction field-effect transistors have been fabricated on Fe-doped semi-insulating InP substrates using liquid-phase epitaxial growth techniques. The authors achieved transconductance of 24 mS (160 mS/mm), drain-source saturation current at an on gate bias of 486 mA/mm and current cutoff frequency of 18.8 GHz using a GaInAsP channel layer owing to the gate length reduction
