Abstract :
Gallium Nitride´s superior physical properties, in comparison with other semiconductors, make GaNHEMT active devices a prime candidate in the implementation of next generation transmitters for radar systems, 3G/4G base stations and WiMAX. In this contribution, the characterization, modelling and verification of different families of high efficiency, high- power devices manufactured at SELEX Sistemi Integrati are reported. Process, characterization and modelling phases are analyzed to improve and refine the technology´s fabrication techniques, thermal degradation issues and dispersion phenomena.
