            Abstract : 
We report on the first metal-oxide-semiconductor AlGaN/GaN radio-frequency (RF) switch with capacitively coupled contacts using a HfO2 layer as the gate dielectric and surface passivation layer. The new insulating-gate RF switch has a lower leakage current and can handle higher RF powers than AlGaN/GaN HFET switches.
