Gallium Nitride (GaN) is a high-performance compound semiconductor. GaN is a III-V direct-bandgap compound semiconductor, just like Gallium Arsenide (GaAs). Compound semiconductors offer an excellent combination of speed and power in many microwave radio frequency (RF) applications.

GaN brings unique advantages to RF applications. GaN's unique material properties provide RF systems with advantages such as high power added efficiency (PAE), high power output, small form factor, wide bandwidth, thermal advantages, and ruggedness.

Many commercial, defense, and aerospace systems use GaN. GaN’s unique advantages enable many new and existing applications, including radar, satellite communications, commercial wireless networks, and cable TV.

GaN is critical to 5G. To meet 5G’s requirements for multi-gigabit speeds and ultra-low latency performance, equipment manufacturers are beginning to deploy high-power GaN in massive multiple-input/multiple-output (MIMO) systems.

GaN can be used throughout the RF front end. GaN was initially used to make power amplifiers (PAs), but is now used in low noise amplifiers (LNAs), high power switches, and mixers.

Multiple GaN process and packaging options support different applications. GaN semiconductor manufacturers have developed a variety of process and packaging options to make it easier for system designers to find the right discrete component, monolithic microwave integrated circuit (MMIC) or module for their specific application.

GaN is extremely reliable, even in harsh environments. With a mean time to failure (MTTF) of more than 10 million hours at 200°C and more than 1 million hours at 225°C, GaN is more reliable than other semiconductor technologies.

GaN is available for high-volume production applications. The U.S. Department of Defense (DOD) has classified GaN as a process at the highest manufacturing readiness level (MRL), MRL 10, meaning full-rate production and lean manufacturing practices are ready.

GaN is opening up new markets. Due to its unique properties, GaN is beginning to expand into many new areas, including automotive, medical systems and advanced scientific applications.

GaN technology will continue to evolve. Future innovations in GaN technology and packaging will enable higher frequencies, higher voltages, and even wider bandwidths, further driving the adoption of GaN.

This will further promote the popularization of GaN. As for its current price advantage, we only know that its charger is a little more expensive.
