Application of GaN

There are many types of gallium nitride (GaN), with Gallium Nitride on Silicon being the most discussed. This technology involves growing GaN materials directly on a silicon substrate. Compared to traditional GaN substrates, Gallium Nitride on Silicon has distinct technical characteristics. It enables low-cost, large-scale manufacturing by utilizing existing silicon processing equipment and manufacturing processes, which gives it significant market potential.

Advantages of GaN:

- Lower on-resistance, leading to reduced conduction losses

- Faster switching speeds, resulting in lower switching losses

- Smaller capacitance, which decreases losses during charging and discharging

- Less power required to drive the circuit

- Smaller devices that reduce the solution footprint on printed circuit boards

- Lower overall costs

Gallium nitride has a variety of application scenarios. In the field of energy electronics, it is widely used in high-frequency switching power supplies, solar inverters, and electric vehicle chargers. Due to its high power and efficiency, gallium nitride offers enhanced power conversion and control capabilities, opening new possibilities in energy electronics.

Another key application area is communications, especially with the development of 5G technology. Gallium nitride serves as the "powerful engine of the 5G era." In 5G wireless communications, it can deliver higher frequencies and broader bandwidths, resulting in faster speeds and more stable signals. This is crucial for achieving high-speed, low-latency wireless communications.

Additionally, gallium nitride is extensively used in lighting, lasers, radar systems, and power management. As the technology matures and costs continue to decline, it is expected to play an increasingly important role across more fields.
