摘要：

A recessed gate AlGaN/GaN HFET with a total gate length of 100μm is studied. The device demonstrates an increase in transconductance from 260.3 to 314.8mS/mm compared to the unrecessed device, while the saturation current changes slightly. Moreover, the ideality is improved from 2.3 to 1.7. An output power density of 11.74W/mm is achieved at 8GHz and 40V using a load pull system.
