About GaN Products and Technology

GaN FETs are a very good fit for satellite applications but require a good gate driver to realize their full potential. Together, they allow more efficient switching, higher frequency operation, reduced gate drive voltage, and smaller solution sizes compared to the traditional silicon counter parts.

In contrast to silicon MOSFETs, GaN FETs do not have a gate oxide layer, and thus gamma radiation does not form traps (holes) to form in a gate oxide layer. GaN is a wide bandgap material. Compared with silicon, the separation between the drain and source can, in theory, be a factor of 10 smaller.

GaN FETs allow power supply designers to further optimize their designs. Advantages for the total power supply include size, weight, efficiency, EMI, and, potentially, fewer voltages and higher loop bandwidth.
