Solid-state power comes in many forms, although the fastest-growing high-frequency, high-power semiconductor technology may be based on gallium nitride (GaN). GaN power transistors have long been the active-device building blocks for linear and compressed power amplifiers in L- and S-band military radar systems.
Depending on design needs, GaN power transistors are available from many suppliers for a variety of applications in circuits and systems for avionics, commercial, industrial, medical, and military use. They all leverage the capabilities of wide-bandgap GaN semiconductor materials to form RF/microwave transistors with high power density and high output-power levels in small packages.
