Silicon Carbide based Gallium Nitride has now been used in the fields of wireless infrastructure (4G/LTE base station), defense and communication satellites. In these areas, the highest performance and reliability must be available. Silicon Carbide based Gallium Nitride is also a strong competitor to 5G MIMO infrastructure.
