This article presents an innovative architecture for the implementation of electrostatic discharge (ESD) protection millimeter-wave (mm-wave) devices. The proposed is based on use 3-dB couplers, whose coupled outputs have been shorted to ground node. In order reduce physical dimensions coupler and reach high coupling required this application, Coupled Slow wave CoPlanar Waveguides (CS-CPWs) was...

The AlN/GaN/AlN heterostructure is attractive for microwave and millimeter-wave power devices due to its thin top barrier, tight carrier confinement, improved breakdown voltage. This work explores the large-signal RF performance of high-electron-mobility transistors on this heterostructure. Results are highlighted by record high on-current 3.6 A/mm, maximum oscillation frequency (f <sub xmlns:m...
