It’s okay to start using gallium-nitride (GaN) devices in your new designs. GaN transistors have become extremely popular in recent years. These wide-bandgap devices have been replacing LDMOS transistors in many power applications. For example, GaN devices are broadly being adopted for new RF power amplifiers used in cellular base stations, radar, satellites, and other high-frequency applications. In general, their ability to endure higher voltages and operate at frequencies well into the millimeter-wave (mmWave) range have them replacing traditional RF power transistors in most amplifier configurations.
