Characteristic of the Recessed-Gate AIGaN/GaN HEMT with a Field Plate

Abstract
Three kinds of AIGaN/GaN HEMTs have been fabricated:(a) non·recessed HEMT without FP HEMT (b) non· recessed FP HEMT,and(c)recessed FP HEMT.Thought contrast the dynamic I-V and microwave measurement to the three devices,we find that the field plate and gate recess can modulate the field in the channel,then suppress the current collapse and enhanced break-down voltage and improve the output power.A lmm gate width device with this structure exhibited a saturated output power of more than 10W.-
