Difference Between Gallium Arsenide/GaAs and Gallium Nitride/GaN RF Power Amplifiers
Radio waves were first mapped out and harnessed back in 1873. Since that time, radio frequencies and microwaves have been used in numerous applications from the telegraph and the first radio broadcasts making their way into people's homes to radar technology and musical instruments. They also paved the way for military drones, satellites, and the internet among other modern-day essentials. GaAs, or gallium arsenide and GaN, or gallium nitride are the 2 most important semiconductor material that are used for building high-power microwave switches and amplifiers, more specifically TR module-based radar assemblies in fighter jets. While GaN has emerged as the leading semiconductor material for high-power microwave switches and amplifiers, GaAs is still the preferred material of choice for low noise. What and Why Are These Used For It's important to understand what semiconductors are and why they're important for RF power amplifiers. Conductors are mate
